Dependencies licenses bundling ?

[aleks-ivanov]

Is there a way/plugin for esbuild to generate a licenses compilation text file, when bundling a Javascript app ?

Documentation is here: https://esbuild.github.io/api/#legal-comments

[aleks-ivanov]

Yes and as I understand legal comments refers to comments inside the source code only and not licenses in a separate file. Correct ?

[evanw]

Yes, the license has to be in the source code. So a comment like // @license MIT will work.

If you want to do something different yourself, I recommend using the metafile, which tells you which files were included in the bundle. Then you can do whatever you like with that information (e.g. looking in each package for LICENSE.md files). This can be done either as an esbuild plugin or just after calling build().
