***This release deliberately contains backwards-incompatible changes.*** To avoid automatically picking up releases like this, you should either be pinning the exact version of `esbuild` in your `package.json` file (recommended) or be using a version range syntax that only accepts patch upgrades such as `^0.23.0` or `~0.23.0`. See npm's documentation about [semver](https://docs.npmjs.com/cli/v6/using-npm/semver/) for more information.
- Drop support for older platforms ([#3902](https://redirect.github.com/evanw/esbuild/pull/3902))
This release drops support for the following operating system:
- macOS 10.15 Catalina
This is because the Go programming language dropped support for this operating system version in Go 1.23, and this release updates esbuild from Go 1.22 to Go 1.23. Go 1.23 now requires macOS 11 Big Sur or later.
Note that this only affects the binary esbuild executables that are published to the esbuild npm package. It's still possible to compile esbuild's source code for these older operating systems. If you need to, you can compile esbuild for yourself using an older version of the Go compiler (before Go version 1.23). That might look something like this:
git clone https://github.com/evanw/esbuild.git
cd esbuild
go build ./cmd/esbuild
./esbuild --version
- Fix class field decorators in TypeScript if `useDefineForClassFields` is `false` ([#3913](https://redirect.github.com/evanw/esbuild/issues/3913))
Setting the `useDefineForClassFields` flag to `false` in `tsconfig.json` means class fields use the legacy TypeScript behavior instead of the standard JavaScript behavior. Specifically they use assign semantics instead of define semantics (e.g. setters are triggered) and fields without an initializer are not initialized at all. However, when this legacy behavior is combined with standard JavaScript decorators, TypeScript switches to always initializing all fields, even those without initializers. Previously esbuild incorrectly continued to omit field initializers for this edge case. These field initializers in this case should now be emitted starting with this release.
- Avoid incorrect cycle warning with `tsconfig.json` multiple inheritance ([#3898](https://redirect.github.com/evanw/esbuild/issues/3898))
TypeScript 5.0 introduced multiple inheritance for `tsconfig.json` files where `extends` can be an array of file paths. Previously esbuild would incorrectly treat files encountered more than once when processing separate subtrees of the multiple inheritance hierarchy as an inheritance cycle. With this release, `tsconfig.json` files containing this edge case should work correctly without generating a warning.
- Handle Yarn Plug'n'Play stack overflow with `tsconfig.json` ([#3915](https://redirect.github.com/evanw/esbuild/issues/3915))
Previously a `tsconfig.json` file that `extends` another file in a package with an `exports` map could cause a stack overflow when Yarn's Plug'n'Play resolution was active. This edge case should work now starting with this release.
- Work around more issues with Deno 1.31+ ([#3917](https://redirect.github.com/evanw/esbuild/pull/3917))
This version of Deno broke the `stdin` and `stdout` properties on command objects for inherited streams, which matters when you run esbuild's Deno module as the entry point (i.e. when `import.meta.main` is `true`). Previously esbuild would crash in Deno 1.31+ if you ran esbuild like that. This should be fixed starting with this release.
This fix was contributed by [@Joshix-1](https://redirect.github.com/Joshix-1).
### [`v0.23.1`](https://redirect.github.com/evanw/esbuild/blob/HEAD/CHANGELOG.md#0231)
[Compare Source](https://redirect.github.com/evanw/esbuild/compare/v0.23.0...v0.23.1)
- Allow using the `node:` import prefix with `es*` targets ([#3821](https://redirect.github.com/evanw/esbuild/issues/3821))
The [`node:` prefix on imports](https://nodejs.org/api/esm.html#node-imports) is an alternate way to import built-in node modules. For example, `import fs from "fs"` can also be written `import fs from "node:fs"`. This only works with certain newer versions of node, so esbuild removes it when you target older versions of node such as with `--target=node14` so that your code still works. With the way esbuild's platform-specific feature compatibility table works, this was added by saying that only newer versions of node support this feature. However, that means that a target such as `--target=node18,es2022` removes the `node:` prefix because none of the `es*` targets are known to support this feature. This release adds the support for the `node:` flag to esbuild's internal compatibility table for `es*` to allow you to use compound targets like this:
```js
// Original code
import fs from 'node:fs'
fs.open
// Old output (with --bundle --format=esm --platform=node --target=node18,es2022)
import fs from "fs";
fs.open;
// New output (with --bundle --format=esm --platform=node --target=node18,es2022)
import fs from "node:fs";
fs.open;
```
- Fix a panic when using the CLI with invalid build flags if `--analyze` is present ([#3834](https://redirect.github.com/evanw/esbuild/issues/3834))
Previously esbuild's CLI could crash if it was invoked with flags that aren't valid for a "build" API call and the `--analyze` flag is present. This was caused by esbuild's internals attempting to add a Go plugin (which is how `--analyze` is implemented) to a null build object. The panic has been fixed in this release.
- Fix incorrect location of certain error messages ([#3845](https://redirect.github.com/evanw/esbuild/issues/3845))
This release fixes a regression that caused certain errors relating to variable declarations to be reported at an incorrect location. The regression was introduced in version 0.18.7 of esbuild.
- Print comments before case clauses in switch statements ([#3838](https://redirect.github.com/evanw/esbuild/issues/3838))
With this release, esbuild will attempt to print comments that come before case clauses in switch statements. This is similar to what esbuild already does for comments inside of certain types of expressions. Note that these types of comments are not printed if minification is enabled (specifically whitespace minification).
- Fix a memory leak with `pluginData` ([#3825](https://redirect.github.com/evanw/esbuild/issues/3825))
With this release, the build context's internal `pluginData` cache will now be cleared when starting a new build. This should fix a leak of memory from plugins that return `pluginData` objects from `onResolve` and/or `onLoad` callbacks.
