• Update to Unicode 15.0.0

  The character tables that determine which characters form valid JavaScript identifiers have been updated from Unicode version 14.0.0 to the newly-released Unicode version 15.0.0. I'm not putting an example in the release notes because all of the new characters will likely just show up as little squares since fonts haven't been updated yet. But you can read https://www.unicode.org/versions/Unicode15.0.0/#Summary for more information about the changes.

• Disallow duplicate lexically-declared names in nested blocks and in strict mode

  In strict mode or in a nested block, it's supposed to be a syntax error to declare two symbols with the same name unless all duplicate entries are either function declarations or all var declarations. However, esbuild was overly permissive and allowed this when duplicate entries were either function declarations or var declarations (even if they were mixed). This check has now been made more restrictive to match the JavaScript specification:

  // JavaScript allows this
  var a
  function a() {}
  {
    var b
    var b
    function c() {}
    function c() {}
  }
  
  // JavaScript doesn't allow this
  {
    var d
    function d() {}
  }

• Add a type declaration for the new empty loader (#​2755)

  I forgot to add this in the previous release. It has now been added.

  This fix was contributed by @​fz6m.

• Add support for the v flag in regular expression literals

  People are currently working on adding a v flag to JavaScript regular expresions. You can read more about this flag here: https://v8.dev/features/regexp-v-flag. This release adds support for parsing this flag, so esbuild will now no longer consider regular expression literals with this flag to be a syntax error. If the target is set to something other than esnext, esbuild will transform regular expression literals containing this flag into a new RegExp() constructor call so the resulting code doesn't have a syntax error. This enables you to provide a polyfill for RegExp that implements the v flag to get your code to work at run-time. While esbuild doesn't typically adopt proposals until they're already shipping in a real JavaScript run-time, I'm adding it now because a) esbuild's implementation doesn't need to change as the proposal evolves, b) this isn't really new syntax since regular expression literals already have flags, and c) esbuild's implementation is a trivial pass-through anyway.

• Avoid keeping the name of classes with static name properties

  The --keep-names property attempts to preserve the original value of the name property for functions and classes even when identifiers are renamed by the minifier or to avoid a name collision. This is currently done by generating code to assign a string to the name property on the function or class object. However, this should not be done for classes with a static name property since in that case the explicitly-defined name property overwrites the automatically-generated class name. With this release, esbuild will now no longer attempt to preserve the name property for classes with a static name property.

• Allow plugins to resolve injected files (#​2754)

  Previously paths passed to the inject feature were always interpreted as file system paths. This meant that onResolve plugins would not be run for them and esbuild's default path resolver would always be used. This meant that the inject feature couldn't be used in the browser since the browser doesn't have access to a file system. This release runs paths passed to inject through esbuild's full path resolution pipeline so plugins now have a chance to handle them using onResolve callbacks. This makes it possible to write a plugin that makes esbuild's inject work in the browser.

• Add the empty loader (#​1541, #​2753)

  The new empty loader tells esbuild to pretend that a file is empty. So for example --loader:.css=empty effectively skips all imports of .css files in JavaScript so that they aren't included in the bundle, since import "./some-empty-file" in JavaScript doesn't bundle anything. You can also use the empty loader to remove asset references in CSS files. For example --loader:.png=empty causes esbuild to replace asset references such as url(image.png) with url() so that they are no longer included in the resulting style sheet.

• Fix </script> and </style> escaping for non-default targets (#​2748)

  The change in version 0.16.0 to give control over </script> escaping via --supported:inline-script=false or --supported:inline-script=true accidentally broke automatic escaping of </script> when an explicit target setting is specified. This release restores the correct automatic escaping of </script> (which should not depend on what target is set to).

• Enable the exports field with NODE_PATHS (#​2752)

  Node has a rarely-used feature where you can extend the set of directories that node searches for packages using the NODE_PATHS environment variable. While esbuild supports this too, previously it only supported the old main field path resolution but did not support the new exports field package resolution. This release makes the path resolution rules the same again for both node_modules directories and NODE_PATHS directories.

New APIs

• New method route.fetch() and new option json for route.fulfill():

  await page.route('**/api/settings', async route => {
    // Fetch original settings.
    const response = await route.fetch();
  
    // Force settings theme to a predefined value.
    const json = await response.json();
    json.theme = 'Solorized';
  
    // Fulfill with modified data.
    await route.fulfill({ json });
  });

• New method locator.all() to iterate over all matching elements:

  // Check all checkboxes!
  const checkboxes = page.getByRole('checkbox');
  for (const checkbox of await checkboxes.all())
    await checkbox.check();

• Retry blocks of code until all assertions pass:

  await expect(async () => {
    const response = await page.request.get('https://api.example.com');
    await expect(response).toBeOK();
  }).toPass();

  Read more in our documentation.

• Automatically capture full page screenshot on test failure:

  // playwright.config.ts
  import type { PlaywrightTestConfig } from '@​playwright/test';
  
  const config: PlaywrightTestConfig = {
    use: {
      screenshot: {
        mode: 'only-on-failure',
