Bumps esbuild to 0.28.1 and updates ancestor dependency wrangler. These dependencies need to be updated together.

Updates esbuild from 0.27.3 to 0.28.1

Release notes

Sourced from esbuild's releases.

v0.28.1

  • Disallow \ in local development server HTTP requests (GHSA-g7r4-m6w7-qqqr)

    This release fixes a security issue where HTTP requests to esbuild's local development server could traverse outside of the serve directory on Windows using a \ backslash character. It happened due to the use of Go's path.Clean() function, which only handles Unix-style / characters. HTTP requests with paths containing \ are no longer allowed.

    Thanks to @​dellalibera for reporting this issue.

  • Add integrity checks to the Deno API (GHSA-gv7w-rqvm-qjhr)

    The previous release of esbuild added integrity checks to esbuild's npm install script. This release also adds integrity checks to esbuild's Deno install script. Now esbuild's Deno API will also fail with an error if the downloaded esbuild binary contains something other than the expected content.

    Note that esbuild's Deno API installs from registry.npmjs.org by default, but allows the NPM_CONFIG_REGISTRY environment variable to override this with a custom package registry. This change means that the esbuild executable served by NPM_CONFIG_REGISTRY must now match the expected content.

    Thanks to @​sondt99 for reporting this issue.

  • Avoid inlining using and await using declarations (#4482)

    Previously esbuild's minifier sometimes incorrectly inlined using and await using declarations into subsequent uses of that declaration, which then fails to dispose of the resource correctly. This bug happened because inlining was done for let and const declarations by avoiding doing it for var declarations, which no longer worked when more declaration types were added. Here's an example:

    // Original code
    {
      using x = new Resource()
      x.activate()
    }
    // Old output (with --minify)
    new Resource().activate();
    // New output (with --minify)
    {using e=new Resource;e.activate()}

  • Fix module evaluation when an error is thrown (#4461, #4467)

    If an error is thrown during module evaluation, esbuild previously didn't preserve the state of the module for subsequent module references. This was observable if import() or require() is used to import a module multiple times. The thrown error is supposed to be thrown by every call to import() or require(), not just the first. With this release, esbuild will now throw the same error every time you call import() or require() on a module that throws during its evaluation.

  • Fix some edge cases around the new operator (#4477)

    Previously esbuild incorrectly printed certain edge cases involving complex expressions inside the target of a new expression (specifically an optional chain and/or a tagged template literal). The generated code for the new target was not correctly wrapped with parentheses, and either contained a syntax error or had different semantics. These edge cases have been fixed so that they now correctly wrap the new target in parentheses. Here is an example of some affected code:

    // Original code
    new (foo()`bar`)()
    new (foo()?.bar)()
    // Old output
    new foo()bar();
    new (foo())?.bar();

Updates wrangler from 4.100.0 to 4.118.0

Release notes

Sourced from wrangler's releases.

wrangler@4.118.0

Minor Changes

  • #14057 cc63aae Thanks @​matingathani! - Add --json flag to wrangler containers info for consistent JSON output with sibling commands list and instances

  • #14944 a249591 Thanks @​nickpatt! - Enable local observability capture by default in dev

    wrangler dev and the Vite plugin now capture request traces and console logs into the Local Explorer's Observability tab out of the box — previously this was opt-in behind X_LOCAL_OBSERVABILITY=true. Set X_LOCAL_OBSERVABILITY=false to opt out (for example if the extra per-worker collector/streaming-tail services cause trouble in a multi-process dev-registry setup).

  • #14919 e0bbf55 Thanks @​avenceslau! - Add additional triggers to Workflows

    Workers can now declaratively start a locally defined Workflow. Configure event subscriptions under triggers.events; Wrangler validates each target and updates the script's event triggers during deployment.

    {
      "triggers": {
        "events": [
          {
            "type": "cf.artifacts.repo.pushed",
            "filter": {
              "namespace": "my-namespace",
              "repo_name": "my-repo"
            },
            "targets": [
              {
                "type": "workflow",
                "workflow_name": "my-workflow"
              }
            ]
          }
        ]
      }
    }

Patch Changes

  • #14936 f92d1fc Thanks @​petebacondarwin! - Fix jsx_fragment being ignored when wrangler dev runs a custom build

    If your project uses a custom build and sets both jsx_factory and jsx_fragment, wrangler dev used your jsx_factory value for JSX fragments as well, so fragments compiled incorrectly. Your jsx_fragment value is now used.

  • #14936 f92d1fc Thanks @​petebacondarwin! - Stop wrangler dev starting new work after you stop it or it reloads

    Stopping wrangler dev, or having it reload after a configuration change, could still leave it starting work for the state it had just left behind: your custom build command could run once more after dev had stopped, a change to a file in your assets directory could be reported against configuration that had already been replaced, and in some cases the process could stay alive instead of exiting.

    That work is now discarded, so stopping or reloading wrangler dev leaves nothing running behind it.

  • #14936 f92d1fc Thanks @​petebacondarwin! - Stop wrangler dev from running custom builds concurrently

    When several watched files changed at once — for example during a git pull or a "save all" — wrangler dev started a custom build for every file that changed, so multiple copies of your build command ran at the same time and fought over the same output files.
