sourcemap
This library implements basic processing of JavaScript sourcemaps.
Installation
The crate is called sourcemap and you can depend on it via cargo:
[dependencies]
sourcemap = "*"
If you want to use the git version:
[dependencies.sourcemap]
git = "https://github.com/getsentry/rust-sourcemap.git"
Basic Operation
This crate can load JavaScript sourcemaps from JSON files. It uses
serde
for parsing of the JSON data. Due to the nature of sourcemaps
the entirety of the file must be loaded into memory which can be quite
memory intensive.
Usage:
use sourcemap::SourceMap;
let input: &[_] = b"{
\"version\":3,
\"sources\":[\"coolstuff.js\"],
\"names\":[\"x\",\"alert\"],
\"mappings\":\"AAAA,GAAIA,GAAI,EACR,IAAIA,GAAK,EAAG,CACVC,MAAM\"
}";
let sm = SourceMap::from_reader(input).unwrap();
let token = sm.lookup_token(0, 0).unwrap(); // line-number and column
println!("token: {}", token);
