Migrate the usage of CommonJS specific code and imports to ESM. Roughly
summarised this:
- Changes all require() calls to import statement or expressions.
- Changes usage of module.exports to export statements.
- Replaces require.resolve with import.meta.resolve.
- Replaces conditional imports with conditional subpath imports.
- Replaces module === require.main with import.meta.main.
- Adds the full filename with extention to all relative imports.
- Changes all usage of __dirname and __filename to their import.meta
equivalents.
- Sets "type": "module" in package.json files.
- Removes usage of "use strict".
- Adds .ts an an alias of .js for the webpack build.
Due to differences in how require and import resolves files the plugin
entrypoints will have to include the filename and extension after this
migration in order to work.
Add option in the controller config to set where static assets are
loaded from in order to support deployments where the static assets are
server via a CDN while the API is directly accessed.
This is useful because some CDNs put low limits on how large requests
bodies can be, which causes issues with uploading large mods and saves.
An instance's factorio.version can now target a release channel such as
"stable" or "experimental" (any key from factorio.com/api/latest-releases)
in addition to "latest" and specific X.Y / X.Y.Z versions.
The controller proxies the latest-releases API through a ValueCache and
persists the last successful response to latest-releases.json, serving that
copy when the API is unreachable. On instance start the host resolves a
channel to the concrete version it points to and feeds it into the existing
checkForUpdates/findVersion path, so a channel auto-installs and runs like a
pinned version. The version selector in the web UI lists the available
channels alongside "latest".
Also clarifies the host log/error when a newer version cannot be downloaded
automatically because the host uses a direct (single-version) Factorio
install rather than a versioned directory.
