v1.1.0
Add ignoreInvalidMapping option to SourceMapGenerator. If enabled, source-map-js will not throw an error on the incorrect previous source map. Instead, it will print warnings and ignore broken mappings.
var generator = new sourceMap.SourceMapGenerator({
file: "my-generated-javascript-file.js",
sourceRoot: "http://example.com/app/js/",
ignoreInvalidMapping: true,
});
