This is a very minimal TS Parser that can be used to parse d.ts files and extract the type information from them.
It is not a full-fledged parser and does not support all the features of TypeScript. It is designed to be used by Ambience to parse lib files.
Usage
import{parse}from"ts-parser/parse/index.ts";constsource=`interface Foo { bar: string;}`;constast=parse(source);
Note
This is not a particularly fast parser, but it is fast enough and structured to be very convenient for Ambience.
Work has been done to make parsing more reasonable by vendoring Arcsecond and optimising it for our usecase (~35x faster parsing with our fork).
Further work will be done in the future.
Benchmark, parsing lib.dom.d.ts:

Time (mean ± σ): 11.850 s ± 0.130 s [User: 12.432 s, System: 0.543 s]
Range (min … max): 11.737 s … 12.177 s 10 runs
= Deno ================
Time (mean ± σ): 5.258 s ± 0.067 s [User: 5.814 s, System: 0.257 s]
Range (min … max): 5.141 s … 5.351 s 10 runs
= Node ================
Time (mean ± σ): 12.571 s ± 0.203 s [User: 13.122 s, System: 0.310 s]
Range (min … max): 12.229 s … 12.891 s 10 runs
=======================
Summary
'deno run -A test.ts' ran
2.25 ± 0.04 times faster than 'bun run test.ts'
2.39 ± 0.05 times faster than 'tsx test.ts'
