v0.23.1

• Allow using the node: import prefix with es* targets (#3821)

  The node: prefix on 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:

  // 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)

  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)

  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)

  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)

  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

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:

0.19.11

• Fix TypeScript-specific class transform edge case (#3559)

  The previous release introduced an optimization that avoided transforming super() in the class constructor for TypeScript code compiled with useDefineForClassFields set to false if all class instance fields have no initializers. The rationale was that in this case, all class instance fields are omitted in the output so no changes to the constructor are needed. However, if all of this is the case and there are #private instance fields with initializers, those private instance field initializers were still being moved into the constructor. This was problematic because they were being inserted before the call to super() (since super() is now no longer transformed in that case). This release introduces an additional optimization that avoids moving the private instance field initializers into the constructor in this edge case, which generates smaller code, matches the TypeScript compiler's output more closely, and avoids this bug:

  // Original code
  class Foo extends Bar {
    #private = 1;
    public: any;
    constructor() {
      super();
    }
  }
  // Old output (with esbuild v0.19.9)
  class Foo extends Bar {
  constructor() {
  super();
  this.#private = 1;
  }
  #private;
  }
  // Old output (with esbuild v0.19.10)
  class Foo extends Bar {
  constructor() {
  this.#private = 1;
  super();
  }
  #private;
  }
  // New output
  class Foo extends Bar {
  #private = 1;
  constructor() {
  super();
  }
  }

• Minifier: allow reording a primitive past a side-effect (#3568)

  The minifier previously allowed reordering a side-effect past a primitive, but didn't handle the case of reordering a primitive past a side-effect. This additional case is now handled:
