esbuild Problem Matchers installs statistics

esbuild-problem-matchers

To use this, add the esbuild or esbuild-watch problem matcher to your tasks.json, as appropriate. For example:

{
  "version": "2.0.0",
  "tasks": [
    {
      "type": "npm",
      "script": "watch",
      "group": "build",
      "problemMatcher": "$esbuild-watch",
      "isBackground": true,
      "label": "npm: watch"
    },
    {
      "type": "npm",
      "script": "build",
      "group": "build",
      "problemMatcher": "$esbuild",
      "label": "npm: build"
    }
  ]
}

ESBuild via CLI Setup

Nothing more is needed for this to work with the esbuild cli.

If you're using an esbuild version before 0.14.1, you should use the $esbuild-0.13 and $esbuild-0.13-watch problem matches instead, as it has different output.

ESBuild via JS

For this problem matcher to be picked up, you need to specify your watch onRebuild property to match what this problem matcher is looking for. For example:

console.log('[watch] build started');

await esbuild
  .build({
    ...otherOptions,
    watch: {
      onRebuild(error, result) {
        console.log('[watch] build started');
        if (error) {
          error.errors.forEach((error) =>
            console.error(
              `> ${error.location.file}:${error.location.line}:${error.location.column}: error: ${error.text}`,
            ),
          );
        } else console.log('[watch] build finished');
      },
    },
  })
  .then(() => {
    console.log('[watch] build finished');
  });
