Bumps esbuild from 0.20.1 to 0.21.5.

Release notes

Sourced from esbuild's releases.

v0.21.5

• Fix Symbol.metadata on classes without a class decorator (#3781)

  This release fixes a bug with esbuild's support for the decorator metadata proposal. Previously esbuild only added the Symbol.metadata property to decorated classes if there was a decorator on the class element itself. However, the proposal says that the Symbol.metadata property should be present on all classes that have any decorators at all, not just those with a decorator on the class element itself.

• Allow unknown import attributes to be used with the copy loader (#3792)

  Import attributes (the with keyword on import statements) are allowed to alter how that path is loaded. For example, esbuild cannot assume that it knows how to load ./bagel.js as type bagel:

  // This is an error with "--bundle" without also using "--external:./bagel.js"
  import tasty from "./bagel.js" with { type: "bagel" }

  Because of that, bundling this code with esbuild is an error unless the file ./bagel.js is external to the bundle (such as with --bundle --external:./bagel.js).

  However, there is an additional case where it's ok for esbuild to allow this: if the file is loaded using the copy loader. That's because the copy loader behaves similarly to --external in that the file is left external to the bundle. The difference is that the copy loader copies the file into the output folder and rewrites the import path while --external doesn't. That means the following will now work with the copy loader (such as with --bundle --loader:.bagel=copy):

  // This is no longer an error with "--bundle" and "--loader:.bagel=copy"
  import tasty from "./tasty.bagel" with { type: "bagel" }

• Support import attributes with glob-style imports (#3797)

  This release adds support for import attributes (the with option) to glob-style imports (dynamic imports with certain string literal patterns as paths). These imports previously didn't support import attributes due to an oversight. So code like this will now work correctly:

  async function loadLocale(locale: string): Locale {
    const data = await import(`./locales/${locale}.data`, { with: { type: 'json' } })
    return unpackLocale(locale, data)
  }

  Previously this didn't work even though esbuild normally supports forcing the JSON loader using an import attribute. Attempting to do this used to result in the following error:

  ✘ [ERROR] No loader is configured for ".data" files: locales/en-US.data
  example.ts:2:28:
    2 │   const data = await import(`./locales/${locale}.data`, { with: { type: 'json' } })
      ╵                             ~~~~~~~~~~~~~~~~~~~~~~~~~~
  
  

  In addition, this change means plugins can now access the contents of with for glob-style imports.

• Support ${configDir} in tsconfig.json files (#3782)

  This adds support for a new feature from the upcoming TypeScript 5.5 release. The character sequence ${configDir} is now respected at the start of baseUrl and paths values, which are used by esbuild during bundling to correctly map import paths to file system paths. This feature lets base tsconfig.json files specified via extends refer to the directory of the top-level tsconfig.json file. Here is an example:
