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 for more information.

• Revert the recent change to avoid bundling dependencies for node (#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)

  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:

  // Original code
  <Foo>
    <Bar />
  </Foo>
  // Old output (with --jsx=preserve)
  <Foo><Bar /></Foo>;
  // New output (with --jsx=preserve)
  <Foo>
  <Bar />
  </Foo>;

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. See npm's documentation about semver for more information.

• Omit packages from bundles by default when targeting node (#1874, #2830, #2846, #2915, #3145, #3294, #3323, #3582, #3809, #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 (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)

  This release drops support for the following operating systems:

  • Windows 7
  • Windows 8
  • Windows Server 2008
  • Windows Server 2012
