overlookmotel	ea2880170a	test(package/codegen): add benchmark with sourcemaps (#25772) ... Add benchmarks for source maps in `oxc-codegen`. 2 benchmarks: 1. Full end-to-end. 2. Without the actual sourcemap generation at the end. The 2nd is to measure the overhead that pushing to the sourcemap arrays adds while printing in isolation.	2026-08-18 16:17:46 +00:00

overlookmotel	a4478e960a	feat(codegen): add oxc-codegen package (#25488) ... Add `oxc-codegen` package - a printer written in TS. ### Features - Prints JS, JSX, TS, TSX. - Matches `oxc_codegen` exactly on all Test262, TypeScript, Acorn-JSX fixtures. - Very fast. ### Deficiencies - Pretty-printing only (no compact/minified output). - No support for printing comments. - Source map support is semi-there, but largely untested, and poor API (design doc has some ideas on how to improve it). ### This PR adds - The printer code. - Conformance testing infra. - Further tests for edge cases. - README. - Design doc - how it differs from `oxc_codegen` and why, what produces the perf. ### This PR doesn't add - Not integrated into CI or release pipeline. ### Notes This started as a slop port of `oxc_codegen`. I've iterated on that base, cleaned it up a lot, and at least skimmed through all of it. I think it's in fairly decent shape. The design doc is I think worth a read. It explains the rationale for the choices, in particular the "1 codebase, 4 builds" approach. I've put it in a new top-level directory called `packages`. It's not an app, so didn't seem to me to fit alongside `apps/oxlint` and `apps/oxfmt`. It's pure JS, so not like e.g. `napi/parser`. And it felt too heavyweight to put into `npm` dir. But maybe there's a better place for it. Co-authored-by: Cameron <cameron.clark@hey.com>	2026-08-12 13:41:31 +00:00
