  • Add support for the mips64le architecture (#523)

    You should now be able to install esbuild on the mips64le architecture. This build target is second-tier as it's not covered by CI, but I tested it in an emulator and it appears to work at the moment.

  • Fix for packages with inconsistent side effect markings

    Packages can have multiple entry points in their package.json file. Two commonly-used ones are specified using the fields main and module. Packages can also mark files in the package as not having side effects using the sideEffects field. Some packages have one entry point marked as having side effects and the other entry point as not having side effects. This is arguably a problem with the package itself. However, this caused an issue with esbuild's automatic entry point field selection method where it would incorrectly consider both main and module to not have side effects if one of them was marked as not having side effects. Now main and module will only be considered to not have side effects if the individual file was marked as not having side effects.

  • Warn about import './file' when ./file was marked as having no side effects

    Files in packages containing "sideEffects": false in the enclosing package.json file are intended to be automatically removed from the bundle if they aren't used. However, code containing import './file' is likely trying to import that file for a side effect. This is a conflict of intentions so it seems like a good idea to warn about this. It's likely a configuration error by the author of the package. The warning points to the location in package.json that caused this situation.

  • Add support for glob-style tests in sideEffects arrays

    The sideEffects field in package.json can optionally contain an array of files that are considered to have side effects. Any file not in that list will be removed if the import isn't used. Webpack supports the * and ? wildcard characters in these file strings. With this release, esbuild supports these wildcard characters too.
