Crate srcmap_generator 

High-performance source map generator (ECMA-426).

Builds source maps incrementally by adding mappings one at a time. Outputs standard source map v3 JSON.

Examples

use srcmap_generator::SourceMapGenerator;

fn main() {
    let mut builder = SourceMapGenerator::new(Some("bundle.js".to_string()));

    let src = builder.add_source("src/app.ts");
    builder.set_source_content(src, "const x = 1;".to_string());

    let name = builder.add_name("x");
    builder.add_named_mapping(0, 0, src, 0, 6, name);
    builder.add_mapping(1, 0, src, 1, 0);

    let json = builder.to_json();
    assert!(json.contains(r#""version":3"#));
    assert!(json.contains(r#""sources":["src/app.ts"]"#));
}
