Bumps esbuild from 0.14.54 to 0.17.0.

Release notes

Sourced from esbuild's releases.

v0.17.0

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 ^0.16.0 or ~0.16.0. See npm's documentation about semver for more information.

At a high level, the breaking changes in this release fix some long-standing issues with the design of esbuild's incremental, watch, and serve APIs. This release also introduces some exciting new features such as live reloading. In detail:

  • Move everything related to incremental builds to a new context API (#1037, #1606, #2280, #2418)

    This change removes the incremental and watch options as well as the serve() method, and introduces a new context() method. The context method takes the same arguments as the build() method but only validates its arguments and does not do an initial build. Instead, builds can be triggered using the rebuild(), watch(), and serve() methods on the returned context object. The new context API looks like this:

    // Create a context for incremental builds
const context = await esbuild.context({
  entryPoints: ['app.ts'],
  bundle: true,
})

    // Manually do an incremental build
const result = await context.rebuild()
    

    // Enable watch mode
await context.watch()
    

    // Enable serve mode
await context.serve()
    

    // Dispose of the context
context.dispose()

    The switch to the context API solves a major issue with the previous API which is that if the initial build fails, a promise is thrown in JavaScript which prevents you from accessing the returned result object. That prevented you from setting up long-running operations such as watch mode when the initial build contained errors. It also makes tearing down incremental builds simpler as there is now a single way to do it instead of three separate ways.

    In addition, this release also makes some subtle changes to how incremental builds work. Previously every call to rebuild() started a new build. If you weren't careful, then builds could actually overlap. This doesn't cause any problems with esbuild itself, but could potentially cause problems with plugins (esbuild doesn't even give you a way to identify which overlapping build a given plugin callback is running on). Overlapping builds also arguably aren't useful, or at least aren't useful enough to justify the confusion and complexity that they bring. With this release, there is now only ever a single active build per context. Calling rebuild() before the previous rebuild has finished now "merges" with the existing rebuild instead of starting a new build.

  • Allow using watch and serve together (#805, #1650, #2576)

    Previously it was not possible to use watch mode and serve mode together. The rationale was that watch mode is one way of automatically rebuilding your project and serve mode is another (since serve mode automatically rebuilds on every request). However, people want to combine these two features to make "live reloading" where the browser automatically reloads the page when files are changed on the file system.

    This release now allows you to use these two features together. You can only call the watch() and serve() APIs once each per context, but if you call them together on the same context then esbuild will automatically rebuild both when files on the file system are changed and when the server serves a request.

  • Support "live reloading" through server-sent events (#802)

    Server-sent events are a simple way to pass one-directional messages asynchronously from the server to the client. Serve mode now provides a /esbuild endpoint with an change event that triggers every time esbuild's output changes. So you can now implement simple "live reloading" (i.e. reloading the page when a file is edited and saved) like this:

    new EventSource('/esbuild').addEventListener('change', () => location.reload())

    The event payload is a JSON object with the following shape:

  • Loader defaults to js for extensionless files (#2776)

    Certain packages contain files without an extension. For example, the yargs package contains the file yargs/yargs which has no extension. Node, Webpack, and Parcel can all understand code that imports yargs/yargs because they assume that the file is JavaScript. However, esbuild was previously unable to understand this code because it relies on the file extension to tell it how to interpret the file. With this release, esbuild will now assume files without an extension are JavaScript files. This can be customized by setting the loader for "" (the empty string, representing files without an extension) to another loader. For example, if you want files without an extension to be treated as CSS instead, you can do that like this:

    • CLI:

      esbuild --bundle --loader:=css

    • JS:

      esbuild.build({
  bundle: true,
  loader: { '': 'css' },
})

    • Go:

      api.Build(api.BuildOptions{
  Bundle: true,
  Loader: map[string]api.Loader{"": api.LoaderCSS},
})

    In addition, the "type" field in package.json files now only applies to files with an explicit .js, .jsx, .ts, or .tsx extension. Previously it was incorrectly applied by esbuild to all files that had an extension other than .mjs, .mts, .cjs, or .cts including extensionless files. So for example an extensionless file in a "type": "module" package is now treated as CommonJS instead of ESM.

0.16.11

  • Avoid a syntax error in the presence of direct eval (#2761)

    The behavior of nested function declarations in JavaScript depends on whether the code is run in strict mode or not. It would be problematic if esbuild preserved nested function declarations in its output because then the behavior would depend on whether the output was run in strict mode or not instead of respecting the strict mode behavior of the original source code. To avoid this, esbuild transforms nested function declarations to preserve the intended behavior of the original source code regardless of whether the output is run in strict mode or not:

    // Original code
if (true) {
  function foo() {}
  console.log(!!foo)
  foo = null
  console.log(!!foo)
}
