使用node.js中的source-map基于JavaScript生成SourceMap

如何解决使用node.js中的source-map基于JavaScript生成SourceMap

无论我做什么，map.toString（）上的地图都是空的。

let path = require("path");
let content = fs.readFileSync(".\\" + file,"utf8");
let filename = path.basename(outFile)
const { code } = js(content);

fs.writeFileSync(outFile,content);
fs.writeFileSync(outMinFile,code);

let gen = new sm.sourceMapGenerator({
    file: filename,sourceRoot: "./",});

gen.setSourceContent("CMS.Layout.js",content);

fs.writeFileSync(outMap,gen.toString());

导致：

{"version":3,"sources":[],"names":[],"mappings":"","file":"CMS.Layout.js","sourceRoot":"./","sourcesContent":[]}

我在做什么错了？

解决方法

我用generate-source-map替换了source-map。容易得多，并且可以在第一次尝试时使用。

let path = require("path");
let content = fs.readFileSync(".\\" + file,"utf8");
let filename = path.basename(outFile)
const { code } = js(content);

fs.writeFileSync(outFile,content);
fs.writeFileSync(outMinFile,code);

let fl = {
    source: content,sourceFile: filename
};

let map = sm(fl);

fs.writeFileSync(outMap,map.toString());
