### [`v0.23.1`](https://togithub.com/evanw/esbuild/blob/HEAD/CHANGELOG.md#0231)
[Compare Source](https://togithub.com/evanw/esbuild/compare/v0.23.0...v0.23.1)
- Allow using the `node:` import prefix with `es*` targets ([#3821](https://togithub.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://togithub.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://togithub.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://togithub.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://togithub.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.
### [`v0.23.0`](https://togithub.com/evanw/esbuild/blob/HEAD/CHANGELOG.md#0230)
[Compare Source](https://togithub.com/evanw/esbuild/compare/v0.22.0...v0.23.0)
***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 `^0.22.0` or `~0.22.0`. See npm's documentation about [semver](https://docs.npmjs.com/cli/v6/using-npm/semver/) for more information.
- Revert the recent change to avoid bundling dependencies for node ([#3819](https://togithub.com/evanw/esbuild/issues/3819))
This release reverts the recent change in version 0.22.0 that made `--packages=external` the default behavior with `--platform=node`. The default is now back to `--packages=bundle`.
I've just been made aware that Amazon doesn't pin their dependencies in their "AWS CDK" product, which means that whenever esbuild publishes a new release, many people (potentially everyone?) using their SDK around the world instantly starts using it without Amazon checking that it works first. This change in version 0.22.0 happened to break their SDK. I'm amazed that things haven't broken before this point. This revert attempts to avoid these problems for Amazon's customers. Hopefully Amazon will pin their dependencies in the future.
In addition, this is probably a sign that esbuild is used widely enough that it now needs to switch to a more complicated release model. I may have esbuild use a beta channel model for further development.
- Fix preserving collapsed JSX whitespace ([#3818](https://togithub.com/evanw/esbuild/issues/3818))
When transformed, certain whitespace inside JSX elements is ignored completely if it collapses to an empty string. However, the whitespace should only be ignored if the JSX is being transformed, not if it's being preserved. This release fixes a bug where esbuild was previously incorrectly ignoring collapsed whitespace with `--jsx=preserve`. Here is an example:
```jsx
// Original code
// Old output (with --jsx=preserve)
;
// New output (with --jsx=preserve)
;
```

[Compare Source](https://togithub.com/evanw/esbuild/compare/v0.21.5...v0.22.0)
**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 `^0.21.0` or `~0.21.0`.

- Omit packages from bundles by default when targeting node ([#1874](https://togithub.com/evanw/esbuild/issues/1874), [#2830](https://togithub.com/evanw/esbuild/issues/2830), [#2846](https://togithub.com/evanw/esbuild/issues/2846), [#2915](https://togithub.com/evanw/esbuild/issues/2915), [#3145](https://togithub.com/evanw/esbuild/issues/3145), [#3294](https://togithub.com/evanw/esbuild/issues/3294), [#3323](https://togithub.com/evanw/esbuild/issues/3323), [#3582](https://togithub.com/evanw/esbuild/issues/3582), [#3809](https://togithub.com/evanw/esbuild/issues/3809), [#3815](https://togithub.com/evanw/esbuild/issues/3815))
This breaking change is an experiment. People are commonly confused when using esbuild to bundle code for node (i.e. for `--platform=node`) because some packages may not be intended for bundlers, and may use node-specific features that don't work with a bundler. Even though esbuild's "getting started" instructions say to use `--packages=external` to work around this problem, many people don't read the documentation and don't do this, and are then confused when it doesn't work. So arguably this is a bad default behavior for esbuild to have if people keep tripping over this.
With this release, esbuild will now omit packages from the bundle by default when the platform is `node` (i.e. the previous behavior of `--packages=external` is now the default in this case). *Note that your dependencies must now be present on the file system when your bundle is run.* If you don't want this behavior, you can do `--packages=bundle` to allow packages to be included in the bundle (i.e. the previous default behavior). Note that `--packages=bundle` doesn't mean all packages are bundled, just that packages are allowed to be bundled. You can still exclude individual packages from the bundle using `--external:` even when `--packages=bundle` is present.
The `--packages=` setting considers all import paths that "look like" package imports in the original source code to be package imports. Specifically import paths that don't start with a path segment of `/` or `.` or `..` are considered to be package imports. The only two exceptions to this rule are [subpath imports](https://nodejs.org/api/packages.html#subpath-imports) (which start with a `#` character) and TypeScript path remappings via `paths` and/or `baseUrl` in `tsconfig.json` (which are applied first).
- Drop support for older platforms ([#3802](https://togithub.com/evanw/esbuild/issues/3802))
This release drops support for the following operating systems:
- Windows 7
- Windows 8
- Windows Server 2008
- Windows Server 2012
This is because the Go programming language dropped support for these operating system versions in [Go 1.21](https://go.dev/doc/go1.21#windows), and this release updates esbuild from Go 1.20 to Go 1.22.
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 1.21). That might look something like this:
git clone https://github.com/evanw/esbuild.git
cd esbuild
go build ./cmd/esbuild
./esbuild.exe --version
In addition, this release increases the minimum required node version for esbuild's JavaScript API from node 12 to node 18. Node 18 is the oldest version of node that is still being supported (see node's [release schedule](https://nodejs.org/en/about/previous-releases) for more information). This increase is because of an incompatibility between the JavaScript that the Go compiler generates for the `esbuild-wasm` package and versions of node before node 17.4 (specifically the `crypto.getRandomValues` function).
- Update `await using` behavior to match TypeScript
TypeScript 5.5 subtly changes the way `await using` behaves. This release updates esbuild to match these changes in TypeScript. You can read more about these changes in [microsoft/TypeScript#58624](https://togithub.com/microsoft/TypeScript/pull/58624).
- Allow `es2024` as a target environment
The ECMAScript 2024 specification was just approved, so it has been added to esbuild as a possible compilation target. You can read more about the features that it adds here: . The only addition that's relevant for esbuild is the regular expression `/v` flag. With `--target=es2024`, regular expressions that use the `/v` flag will now be passed through untransformed instead of being transformed into a call to `new RegExp`.
- Publish binaries for OpenBSD on 64-bit ARM ([#3665](https://togithub.com/evanw/esbuild/issues/3665), [#3674](https://togithub.com/evanw/esbuild/pull/3674))
With this release, you should now be able to install the `esbuild` npm package in OpenBSD on 64-bit ARM, such as on an Apple device with an M1 chip.
This was contributed by [@ikmckenz](https://togithub.com/ikmckenz).
- Publish binaries for WASI (WebAssembly System Interface) preview 1 ([#3300](https://togithub.com/evanw/esbuild/issues/3300), [#3779](https://togithub.com/evanw/esbuild/pull/3779))
The upcoming WASI (WebAssembly System Interface) standard is going to be a way to run WebAssembly outside of a JavaScript host environment. In this scenario you only need a `.wasm` file without any supporting JavaScript code. Instead of JavaScript providing the APIs for the host environment, the WASI standard specifies a "system interface" that WebAssembly code can access directly (e.g. for file system access).
Development versions of the WASI specification are being released using preview numbers. The people behind WASI are currently working on preview 2 but the Go compiler has [released support for preview 1](https://go.dev/blog/wasi), which from what I understand is now considered an unsupported legacy release. However, some people have requested that esbuild publish binary executables that support WASI preview 1 so they can experiment with them.
This release publishes esbuild precompiled for WASI preview 1 to the `@esbuild/wasi-preview1` package on npm (specifically the file `@esbuild/wasi-preview1/esbuild.wasm`). This binary executable has not been tested and won't be officially supported, as it's for an old preview release of a specification that has since moved in another direction. If it works for you, great! If not, then you'll likely have to wait for the ecosystem to evolve before using esbuild with WASI. For example, it sounds like perhaps WASI preview 1 doesn't include support for opening network sockets so esbuild's local development server is unlikely to work with WASI preview 1.
- Warn about `onResolve` plugins not setting a path ([#3790](https://togithub.com/evanw/esbuild/issues/3790))
Plugins that return values from `onResolve` without resolving the path (i.e. without setting either `path` or `external: true`) will now cause a warning. This is because esbuild only uses return values from `onResolve` if it successfully resolves the path, and it's not good for invalid input to be silently ignored.
- Add a new Go API for running the CLI with plugins ([#3539](https://togithub.com/evanw/esbuild/pull/3539))
With esbuild's Go API, you can now call `cli.RunWithPlugins(args, plugins)` to pass an array of esbuild plugins to be used during the build process. This allows you to create a CLI that behaves similarly to esbuild's CLI but with additional Go plugins enabled.
