Inputs

name	description	required	default
name	The name of your project. This will be used in the comment header.	no	${{ github.event.repository.name }}
metafiles	A comma-separated list of paths to [esbuild's meta file]([https://esbuild.github.io/api/#metafile]). Must be non-empty. Glob (`dist/*/meta.json`) is supported. As of esbuild v0.20.0, you need to write the meta file by yourself after build, something like this: ```javascript import as esbuild from 'esbuild' import fs from 'node:fs' let result = await esbuild.build({ entryPoints: ['src/app1.js', 'src/app2.js'], bundle: true, metafile: true, outdir: 'dist', }) fs.writeFileSync('dist/meta.json', JSON.stringify(result.metafile)) ``` In this case, the `metafiles` config should be `"dist/meta.json"`. Typically, you only need one meta file since one meta file can contain multiple out files information. Multiple meta files may be useful for more complex scenarios.	yes	—
analyze_directory	A path to working directory where bundle analysis are stored.	no	.analyzer
include_extensions	A comma-separated list of file extension to be included in the analysis table.	no	.js,.cjs,.mjs
percent_extra_attention	If an out file size has increased more than this percent, display a "‼️" to draw attention to the change.	no	20
include_size_comparison	A comma-separated list of size comparison items to be displayed. Available filter are `total`, `added`, `deleted`, `increased`, `decreased` and `no-change`. If you are not interested in some of them, you can remove them from the list.	no	added, deleted, increased, decreased, no-change
show_details	If `true`, a collapsed "details" section is rendered. It explains the details of the numbers provided and icons.	no	true
show_no_change	If `true`, all bundles are shown in the analysis regardless of size change. If `false`, only bundles with size changes are shown.	no	—
top_n_largest_paths	The number of largest paths (e.g.) `node_modules/foo`) to be collected. If 0 or lower, skipped.	no	20
