SnapFire Compiler
Compile TypeScript for the browser. No Node.js required. It reads your sources, emits browser-native ES modules and stops if an import cannot be resolved. The binary is snapfirec.
No node_modules
Third-party libraries live in a committed vendor tree and resolve through a native browser import map. Nothing is fetched at build time that was not checked in.
The import map is the check
Pass --import-map and a bare import with no entry fails the build instead of failing in a browser tab.
One binary
Native and SWC-backed. There is no toolchain to install beside it and no configuration file it needs to start.
A build
What FSR runs for you, and what you run on its own.
snapfirec --source-map --minify compact \
--public-path /static/js/app \
--import-map ../public/js/importmap.json| Flag | What it does |
|---|---|
--source-map | Writes a .map beside every output. |
--minify compact | Minifies without mangling what a stack trace needs. |
--public-path <prefix> | The URL prefix the browser fetches the outputs under. |
--import-map <file> | Fails the build when a bare import has no entry. |
Where it sits
FSR uses the compiler to bundle the browser half of an application, but the dependency runs one way: the compiler knows nothing about FSR, plan files or routes. It is a TypeScript and CSS compiler you can point at any project, including one served by snapfire.
