fromSourceMap(sourceMap: SourceMapGenerator, sourceMapUrl?: SourceMapUrl): Promise<BasicSourceMapConsumer>
[src]Create a BasicSourceMapConsumer from a SourceMapGenerator.
@param sourceMap
The source map that will be consumed.

[src]rawSourceMap: RawSourceMap | RawIndexMap | string,
sourceMapUrl: SourceMapUrl | null | undefined,
callback: (consumer: BasicSourceMapConsumer | IndexedSourceMapConsumer) => Promise<T> | T,
): Promise<T>Construct a new SourceMapConsumer from rawSourceMap and sourceMapUrl
(see the SourceMapConsumer constructor for details. Then, invoke the async function f(SourceMapConsumer) -> T with the newly constructed consumer, wait
for f to complete, call destroy on the consumer, and return f's return
value.
You must not use the consumer after f completes!
By using with, you do not have to remember to manually call destroy on
the consumer, since it will be called automatically once f completes.
const xSquared = await SourceMapConsumer.with(
myRawSourceMap,
null,
async function (consumer) {
// Use `consumer` inside here and don't worry about remembering
// to call `destroy`.
const x = await whatever(consumer);
return x * x;
}
);
// You may not use that `consumer` anymore out here; it has
// been destroyed. But you can use `xSquared`.
console.log(xSquared);
