[Compare Source](https://togithub.com/rollup/rollup/compare/v2.79.1...v3.0.0)
*2022-10-11*
##### Breaking Changes
##### General Changes
- Rollup now requires at least Node 14.18.0 to run ([#4548](https://togithub.com/rollup/rollup/issues/4548) and [#4596](https://togithub.com/rollup/rollup/issues/4596))
- The browser build has been split into a separate package `@rollup/browser` ([#4593](https://togithub.com/rollup/rollup/issues/4593))
- The node build uses the `node:` prefix for imports of builtin modules ([#4596](https://togithub.com/rollup/rollup/issues/4596))
- Some previously deprecated features have been removed ([#4552](https://togithub.com/rollup/rollup/issues/4552)):
- Some plugin context functions have been removed:
- `this.emitAsset()`: use `this.emitFile()`
- `this.emitChunk()`: use `this.emitFile()`
- `this.getAssetFileName()`: use `this.getFileName()`
- `this.getChunkFileName()`: use `this.getFileName()`
- `this.isExternal()`: use `this.resolve()`
- `this.resolveId()`: use `this.resolve()`
- The `resolveAssetUrl` plugin hook has been removed: use `resolveFileUrl`
- Rollup no longer passes `assetReferenceId` or `chunkReferenceId` parameters to `resolveFileUrl`
- The `treeshake.pureExternalModules` option has been removed: use `treeshake.moduleSideEffects: 'no-external'`
- You may no longer use `true` or `false` for `output.interop`. As a replacement for `true`, you can use "compat"
- Emitted assets no longer have an `isAsset` flag in the bundle
- Rollup will no longer fix assets added directly to the bundle by adding the `type: "asset"` field
- Some features that were previously marked for deprecation now show warnings when used ([#4552](https://togithub.com/rollup/rollup/issues/4552)):
- Some options have been deprecated:
- `inlineDynamicImports` as part of the input options: use `output. inlineDynamicImports`
- `manualChunks` as part of the input options: use ` output. manualChunks `
- `maxParallelFileReads`: use \`maxParallelFileOps
- `output.preferConst`: use `output.generatedCode.constBindings`
- `output.dynamicImportFunction`: use the `renderDynamicImport` plugin hook
- `output.namespaceToStringTag`: use `output.generatedCode.symbols`
- `preserveModules` as part of the input options: use ` output. preserveModules `
- You should no longer access `this.moduleIds` in plugins: use `this.getModuleIds()`
- You should no longer access `this.getModuleInfo(...).hasModuleSideEffects` in plugins: use `this.getModuleInfo(...).moduleSideEffects`
- Configuration files are only bundled if either the `--configPlugin` or the `--bundleConfigAsCjs` options are used. The configuration is bundled to an ES module unless the `--bundleConfigAsCjs` option is used. In all other cases, configuration is now loaded using Node's native mechanisms ([#4574](https://togithub.com/rollup/rollup/issues/4574) and [#4621](https://togithub.com/rollup/rollup/issues/4621))
- The properties attached to some errors have been changed so that there are fewer different possible properties with consistent types ([#4579](https://togithub.com/rollup/rollup/issues/4579))
- Some errors have been replaced by others (ILLEGAL_NAMESPACE_REASSIGNMENT -> ILLEGAL_REASSIGNMENT, NON_EXISTENT_EXPORT -> MISSING_EXPORT) ([#4579](https://togithub.com/rollup/rollup/issues/4579))
- Files in `rollup/dist/*` can only be required using their file extension ([#4581](https://togithub.com/rollup/rollup/issues/4581))
- The `loadConfigFile` helper now has a named export of the same name instead of a default export ([#4581](https://togithub.com/rollup/rollup/issues/4581))
- When using the API and sourcemaps, sourcemap comments are contained in the emitted files and sourcemaps are emitted as regular assets ([#4605](https://togithub.com/rollup/rollup/issues/4605))
- Watch mode no longer uses Node's EventEmitter but a custom implementation that awaits Promises returned from event handlers ([#4609](https://togithub.com/rollup/rollup/issues/4609))
- Assets may only be deduplicated with previously emitted assets if their source is a `string` ([#4644](https://togithub.com/rollup/rollup/issues/4644))
- By default, Rollup will keep external dynamic imports as `import(…)` in commonjs output unless `output.dynamicImportInCjs` is set to false ([#4647](https://togithub.com/rollup/rollup/issues/4647))
##### Changes to Rollup Options
- As functions passed to `output.banner/footer/intro/outro` are now called per-chunk, they should be careful to avoid performance-heavy operations ([#4543](https://togithub.com/rollup/rollup/issues/4543))
- `entryFileNames/chunkFileNames` functions now longer have access to the rendered module information via `modules`, only to a list of included `moduleIds` ([#4543](https://togithub.com/rollup/rollup/issues/4543))
- The path of a module is no longer prepended to the corresponding chunk when preserving modules ([#4565](https://togithub.com/rollup/rollup/issues/4565))
- When preserving modules, the `[name]` placeholder (as well as the `chunkInfo.name` property when using a function) now includes the relative path of the chunk as well as optionally the file extension if the extension is not one of `.js`, `.jsx`, `.mjs`, `.cjs`, `.ts`, `.tsx`, `.mts`, or `.cts` ([#4565](https://togithub.com/rollup/rollup/issues/4565))
- The `[ext]`, `[extName]` and `[assetExtName]` placeholders are no longer supported when preserving modules ([#4565](https://togithub.com/rollup/rollup/issues/4565))
- The `perf` option no longer collects timings for the asynchronous part of plugin hooks as the readings were wildly inaccurate and very misleading, and timings are adapted to the new hashing algorithm ([#4566](https://togithub.com/rollup/rollup/issues/4566))
- Change the default value of `makeAbsoluteExternalsRelative` to "ifRelativeSource" so that absolute external imports will no longer become relative imports in the output, while relative external imports will still be renormalized ([#4567](https://togithub.com/rollup/rollup/issues/4567))
- Change the default for `output.generatedCode.reservedNamesAsProps` to no longer quote properties like `default` by default ([#4568](https://togithub.com/rollup/rollup/issues/4568))
- Change the default for `preserveEntrySignatures` to "exports-only" so that by default, empty facades for entry chunks are no longer created ([#4576](https://togithub.com/rollup/rollup/issues/4576))
- Change the default for `output.interop` to "default" to better align with NodeJS interop ([#4611](https://togithub.com/rollup/rollup/issues/4611))
- Change the default for `output.esModule` to "if-default-prop", which only adds \__esModule when the default export would be a property ([#4611](https://togithub.com/rollup/rollup/issues/4611))
- Change the default for `output.systemNullSetters` to `true`, which requires at least SystemJS 6.3.3 ([#4649](https://togithub.com/rollup/rollup/issues/4649))
##### Plugin API Changes
- Plugins that add/change/remove imports or exports in `renderChunk` should make sure to update `ChunkInfo.imports/importedBindings/exports` accordingly ([#4543](https://togithub.com/rollup/rollup/issues/4543))
- The order of plugin hooks when generating output has changed ([#4543](https://togithub.com/rollup/rollup/issues/4543))
- Chunk information passed to `renderChunk` now contains names with hash placeholders instead of final names, which will be replaced when used in the returned code or `ChunkInfo.imports/importedBindings/exports` ([#4543](https://togithub.com/rollup/rollup/issues/4543) and [#4631](https://togithub.com/rollup/rollup/issues/4631))
- Hooks defined in output plugins will now run after hooks defined in input plugins (used to be the other way around) ([#3846](https://togithub.com/rollup/rollup/issues/3846))
##### Features
- Functions passed to `output.banner/footer/intro/outro` are now called per-chunk with some chunk information ([#4543](https://togithub.com/rollup/rollup/issues/4543))
- Plugins can access the entire chunk graph via an additional parameter in `renderChunk` ([#4543](https://togithub.com/rollup/rollup/issues/4543))
- Chunk hashes only depend on the actual content of the chunk and are otherwise stable against things like renamed/moved source files or changed module resolution order ([#4543](https://togithub.com/rollup/rollup/issues/4543))
- The length of generated file hashes can be customized both globally and per-chunk ([#4543](https://togithub.com/rollup/rollup/issues/4543))
- When preserving modules, the regular `entryFileNames` logic is used and the path is included in the `[name]` property. This finally gives full control over file names when preserving modules ([#4565](https://togithub.com/rollup/rollup/issues/4565))
- `output.entryFileNames` now also supports the `[hash]` placeholder when preserving modules ([#4565](https://togithub.com/rollup/rollup/issues/4565))
- The `perf` option will now collect (synchronous) timings for all plugin hooks, not just a small selection ([#4566](https://togithub.com/rollup/rollup/issues/4566))
- All errors thrown by Rollup have `name: RollupError` now to make clearer that those are custom error types ([#4579](https://togithub.com/rollup/rollup/issues/4579))
- Error properties that reference modules (such as id and ids) will now always contain the full ids. Only the error message will use shortened ids ([#4579](https://togithub.com/rollup/rollup/issues/4579))
- Errors that are thrown in response to other errors (e.g. parse errors thrown by acorn) will now use the standardized cause property to reference the original error ([#4579](https://togithub.com/rollup/rollup/issues/4579))
- If sourcemaps are enabled, files will contain the appropriate sourcemap comment in `generateBundle` and sourcemap files are available as regular assets ([#4605](https://togithub.com/rollup/rollup/issues/4605))
- Returning a Promise from an event handler attached to a RollupWatcher instance will make Rollup wait for the Promise to resolve ([#4609](https://togithub.com/rollup/rollup/issues/4609))
- There is a new value "compat" for output.interop that is similar to "auto" but uses duck-typing to determine if there is a default export ([#4611](https://togithub.com/rollup/rollup/issues/4611))
- There is a new value "if-default-prop" for esModule that only adds an `__esModule` marker to the bundle if there is a default export that is rendered as a property ([#4611](https://togithub.com/rollup/rollup/issues/4611))
- Rollup can statically resolve checks for `foo[Symbol.toStringTag]` to "Module" if foo is a namespace ([#4611](https://togithub.com/rollup/rollup/issues/4611))
- There is a new CLI option `--bundleConfigAsCjs` which will force the configuration to be bundled to CommonJS ([#4621](https://togithub.com/rollup/rollup/issues/4621))
- Import assertions for external imports that are present in the input files will be retained in ESM output ([#4646](https://togithub.com/rollup/rollup/issues/4646))
- Rollup will warn when a module is imported with conflicting import assertions ([#4646](https://togithub.com/rollup/rollup/issues/4646))
- Plugins can add, remove or change import assertions when resolving ids ([#4646](https://togithub.com/rollup/rollup/issues/4646))
- The `output.externalImportAssertions` option allows to turn off emission of import assertions ([#4646](https://togithub.com/rollup/rollup/issues/4646))
- Use `output.dynamicImportInCjs` to control if dynamic imports are emitted as `import(…)` or wrapped `require(…)` when generating commonjs output ([#4647](https://togithub.com/rollup/rollup/issues/4647))
##### Bug Fixes
- Chunk hashes take changes in `renderChunk`, e.g. minification, into account ([#4543](https://togithub.com/rollup/rollup/issues/4543))
- Hashes of referenced assets are properly reflected in the chunk hash ([#4543](https://togithub.com/rollup/rollup/issues/4543))
- No longer warn about implicitly using default export mode to not tempt users to switch to named export mode and break Node compatibility ([#4624](https://togithub.com/rollup/rollup/issues/4624))
- Avoid performance issues when emitting thousands of assets ([#4644](https://togithub.com/rollup/rollup/issues/4644))

Rollup now requires at least Node 14.18.0 to run ([#4548](https://togithub.com/rollup/rollup/issues/4548) and [#4596](https://togithub.com/rollup/rollup/issues/4596)) - The browser build has been split into a separate package `@rollup/browser` ([#4593](https://togithub.com/rollup/rollup/issues/4593)) - The node build uses the `node:` prefix for imports of builtin modules ([#4596](https://togithub.com/rollup/rollup/issues/4596)) - Some previously deprecated features have been removed ([#4552](https://togithub.com/rollup/rollup/issues/4552)): - Some plugin context functions have been removed: - `this.emitAsset()`: use `this.emitFile()` - `this.emitChunk()`: use `this.emitFile()` - `this.getAssetFileName()`: use `this.getFileName()` - `this.getChunkFileName()`: use `this.getFileName()` - `this.isExternal()`: use `this.resolve()` - `this.resolveId()`: use `this.resolve()` - The `resolveAssetUrl` plugin hook has been removed: use `resolveFileUrl` - Rollup no longer passes `assetReferenceId` or `chunkReferenceId` parameters to `resolveFileUrl` - The `treeshake.pureExternalModules` option has been removed: use `treeshake.moduleSideEffects: 'no-external'` - You may no longer use `true` or `false` for `output.interop`. As a replacement for `true`, you can use "compat" - Emitted assets no longer have an `isAsset` flag in the bundle - Rollup will no longer fix assets added directly to the bundle by adding the `type: "asset"` field - Some features that were previously marked for deprecation now show warnings when used ([#4552](https://togithub.com/rollup/rollup/issues/4552)): - Some options have been deprecated: - `inlineDynamicImports` as part of the input options: use `output. inlineDynamicImports` - `manualChunks` as part of the input options: use ` output. manualChunks ` - `maxParallelFileReads`: use \`maxParallelFileOps - `output.preferConst`: use `output.generatedCode.constBindings` - `output.dynamicImportFunction`: use the `renderDynamicImport` plugin hook - `output.namespaceToStringTag`: use `output.generatedCode.symbols` - `preserveModules` as part of the input options: use ` output. preserveModules ` - You should no longer access `this.moduleIds` in plugins: use `this.getModuleIds()` - You should no longer access `this.getModuleInfo(...).hasModuleSideEffects` in plugins: use `this.getModuleInfo(...).moduleSideEffects` - Configuration files are only bundled if either the `--configPlugin` or the `--bundleConfigAsCjs` options are used. The configuration is bundled to an ES module unless the `--bundleConfigAsCjs` option is used. In all other cases, configuration is now loaded using Node's native mechanisms ([#4574](https://togithub.com/rollup/rollup/issues/4574) and [#4621](https://togithub.com/rollup/rollup/issues/4621)) - The properties attached to some errors have been changed so that there are fewer different possible properties with consistent types ([#4579](https://togithub.com/rollup/rollup/issues/4579)) - Some errors have been replaced by others (ILLEGAL_NAMESPACE_REASSIGNMENT -> ILLEGAL_REASSIGNMENT, NON_EXISTENT_EXPORT -> MISSING_EXPORT) ([#4579](https://togithub.com/rollup/rollup/issues/4579)) - Files in `rollup/dist/*` can only be required using their file extension ([#4581](https://togithub.com/rollup/rollup/issues/4581)) - The `loadConfigFile` helper now has a named export of the same name instead of a default export ([#4581](https://togithub.com/rollup/rollup/issues/4581)) - When using the API and sourcemaps, sourcemap comments are contained in the emitted files and sourcemaps are emitted as regular assets ([#4605](https://togithub.com/rollup/rollup/issues/4605)) - Watch mode no longer uses Node's EventEmitter but a custom implementation that awaits Promises returned from event handlers ([#4609](https://togithub.com/rollup/rollup/issues/4609)) - Assets may only be deduplicated with previously emitted assets if their source is a `string` ([#4644](https://togithub.com/rollup/rollup/issues/4644)) - By default, Rollup will keep external dynamic imports as `import(…)` in commonjs output unless `output.dynamicImportInCjs` is set to false ([#4647](https://togithub.com/rollup/rollup/issues/4647)) ##### Changes to Rollup Options - As functions passed to `output.banner/footer/intro/outro` are now called per-chunk, they should be careful to avoid performance-heavy operations ([#4543](https://togithub.com/rollup/rollup/issues/4543)) - `entryFileNames/chunkFileNames` functions now longer have access to the rendered module information via `modules`, only to a list of included `moduleIds` ([#4543](https://togithub.com/rollup/rollup/issues/4543)) - The path of a module is no longer prepended to the corresponding chunk when preserving modules ([#4565](https://togithub.com/rollup/rollup/issues/4565)) - When preserving modules, the `[name]` placeholder (as well as the `chunkInfo.name` property when using a function) now includes the relative path of the chunk as well as optionally the file extension if the extension is not one of `.js`, `.jsx`, `.mjs`, `.cjs`, `.ts`, `.tsx`, `.mts`, or `.cts` ([#4565](https://togithub.com/rollup/rollup/issues/4565)) - The `[ext]`, `[extName]` and `[assetExtName]` placeholders are no longer supported when preserving modules ([#4565](https://togithub.com/rollup/rollup/issues/4565)) - The `perf` option no longer collects timings for the asynchronous part of plugin hooks as the readings were wildly inaccurate and very misleading, and timings are adapted to the new hashing algorithm ([#4566](https://togithub.com/rollup/rollup/issues/4566)) - Change the default value of `makeAbsoluteExternalsRelative` to "ifRelativeSource" so that absolute external imports will no longer become relative imports in the output, while relative external imports will still be renormalized ([#4567](https://togithub.com/rollup/rollup/issues/4567)) - Change the default for `output.generatedCode.reservedNamesAsProps` to no longer quote properties like `default` by default ([#4568](https://togithub.com/rollup/rollup/issues/4568)) - Change the default for `preserveEntrySignatures` to "exports-only" so that by default, empty facades for entry chunks are no longer created ([#4576](https://togithub.com/rollup/rollup/issues/4576)) - Change the default for `output.interop` to "default" to better align with NodeJS interop ([#4611](https://togithub.com/rollup/rollup/issues/4611)) - Change the default for `output.esModule` to "if-default-prop", which only adds \__esModule when the default export would be a property ([#4611](https://togithub.com/rollup/rollup/issues/4611)) - Change the default for `output.systemNullSetters` to `true`, which requires at least SystemJS 6.3.3 ([#4649](https://togithub.com/rollup/rollup/issues/4649)) ##### Plugin API Changes - Plugins that add/change/remove imports or exports in `renderChunk` should make sure to update `ChunkInfo.imports/importedBindings/exports` accordingly ([#4543](https://togithub.com/rollup/rollup/issues/4543)) - The order of plugin hooks when generating output has changed ([#4543](https://togithub.com/rollup/rollup/issues/4543)) - Chunk information passed to `renderChunk` now contains names with hash placeholders instead of final names, which will be replaced when used in the returned code or `ChunkInfo.imports/importedBindings/exports` ([#4543](https://togithub.com/rollup/rollup/issues/4543) and [#4631](https://togithub.com/rollup/rollup/issues/4631)) - Hooks defined in output plugins will now run after hooks defined in input plugins (used to be the other way around) ([#3846](https://togithub.com/rollup/rollup/issues/3846)) ##### Features - Functions passed to `output.banner/footer/intro/outro` are now called per-chunk with some chunk information ([#4543](https://togithub.com/rollup/rollup/issues/4543)) - Plugins can access the entire chunk graph via an additional parameter in `renderChunk` ([#4543](https://togithub.com/rollup/rollup/issues/4543)) - Chunk hashes only depend on the actual content of the chunk and are otherwise stable against things like renamed/moved source files or changed module resolution order ([#4543](https://togithub.com/rollup/rollup/issues/4543)) - The length of generated file hashes can be customized both globally and per-chunk ([#4543](https://togithub.com/rollup/rollup/issues/4543)) - When preserving modules, the regular `entryFileNames` logic is used and the path is included in the `[name]` property. This finally gives full control over file names when preserving modules ([#4565](https://togithub.com/rollup/rollup/issues/4565)) - `output.entryFileNames` now also supports the `[hash]` placeholder when preserving modules ([#4565](https://togithub.com/rollup/rollup/issues/4565)) - The `perf` option will now collect (synchronous) timings for all plugin hooks, not just a small selection ([#4566](https://togithub.com/rollup/rollup/issues/4566)) - All errors thrown by Rollup have `name: RollupError` now to make clearer that those are custom error types ([#4579](https://togithub.com/rollup/rollup/issues/4579)) - Error properties that reference modules (such as id and ids) will now always contain the full ids. Only the error message will use shortened ids ([#4579](https://togithub.com/rollup/rollup/issues/4579)) - Errors that are thrown in response to other errors (e.g. parse errors thrown by acorn) will now use the standardized cause property to reference the original error ([#4579](https://togithub.com/rollup/rollup/issues/4579)) - If sourcemaps are enabled, files will contain the appropriate sourcemap comment in `generateBundle` and sourcemap files are available as regular assets ([#4605](https://togithub.com/rollup/rollup/issues/4605)) - Returning a Promise from an event handler attached to a RollupWatcher instance will make Rollup wait for the Promise to resolve ([#4609](https://togithub.com/rollup/rollup/issues/4609)) - There is a new value "compat" for output.interop that is similar to "auto" but uses duck-typing to determine if there is a default export ([#4611](https://togithub.com/rollup/rollup/issues/4611)) - There is a new value "if-default-prop" for esModule that only adds an `__esModule` marker to the bundle if there is a default export that is rendered as a property ([#4611](https://togithub.com/rollup/rollup/issues/4611)) - Rollup can statically resolve checks for `foo[Symbol.toStringTag]` to "Module" if foo is a namespace ([#4611](https://togithub.com/rollup/rollup/issues/4611)) - There is a new CLI option `--bundleConfigAsCjs` which will force the configuration to be bundled to CommonJS ([#4621](https://togithub.com/rollup/rollup/issues/4621)) - Import assertions for external imports that are present in the input files will be retained in ESM output ([#4646](https://togithub.com/rollup/rollup/issues/4646)) - Rollup will warn when a module is imported with conflicting import assertions ([#4646](https://togithub.com/rollup/rollup/issues/4646)) - Plugins can add, remove or change import assertions when resolving ids ([#4646](https://togithub.com/rollup/rollup/issues/4646)) - The `output.externalImportAssertions` option allows to turn off emission of import assertions ([#4646](https://togithub.com/rollup/rollup/issues/4646)) - Use `output.dynamicImportInCjs` to control if dynamic imports are emitted as `import(…)` or wrapped `require(…)` when generating commonjs output ([#4647](https://togithub.com/rollup/rollup/issues/4647)) ##### Bug Fixes - Chunk hashes take changes in `renderChunk`, e.g. minification, into account ([#4543](https://togithub.com/rollup/rollup/issues/4543)) - Hashes of referenced assets are properly reflected in the chunk hash ([#4543](https://togithub.com/rollup/rollup/issues/4543)) - No longer warn about implicitly using default export mode to not tempt users to switch to named export mode and break Node compatibility ([#4624](https://togithub.com/rollup/rollup/issues/4624)) - Avoid performance issues when emitting thousands of assets ([#4644](https://togithub.com/rollup/rollup/issues/4644)) ##### Pull Requests -
