[theia-dev] Theia 1.77: runtime packages switch to ES modules

[Nina Doschek <ndoschek@xxxxxxxxxxxxxxxxx>]

Hi everyone,

Theia 1.77 switches the runtime packages (packages/*) from CommonJS to ES modules.
Most applications and extensions will keep working without changes, but please check your code against the migration guide, especially direct imports of shared libraries like
inversify, constructor injection without @inject, and esbuild customizations: https://github.com/eclipse-theia/theia/blob/master/doc/Migration.md#v1770

The change is included in the "next" builds from 1.77.0-next.101 on (e.g. https://www.npmjs.com/package/@theia/core/v/1.77.0-next.101), so you can already try it.
Please report problems and questions in this discussion: https://github.com/eclipse-theia/theia/discussions/18312

Open pull requests: the change touches almost every file in packages/*, so most open PRs will have conflicts and need a rebase.
See also the discussion entry for more information on how to deal with that.

Thanks,
Nina
