示例1: generateSourceMap
function generateSourceMap(
filename: string,
source: string,
generated: string,
sourceRoot: string
): RawSourceMap {
const map = new SourceMapGenerator({
file: filename.replace(/\\/g, '/'),
sourceRoot: sourceRoot.replace(/\\/g, '/')
})
map.setSourceContent(filename, source)
generated.split(splitRE).forEach((line, index) => {
if (!emptyRE.test(line)) {
map.addMapping({
source: filename,
original: {
line: index + 1,
column: 0
},
generated: {
line: index + 1,
column: 0
}
})
}
})
return map.toJSON()
}示例2: createJsIdentitySourcemap
/**
* Creates an identity source map from JS script content. Can offset original
* line/column data for inline script elements.
*/

sourceUrl: string,
sourceContent: string,
lineOffset: number,
firstLineCharOffset: number) {
