MAPS SOURCES CODE

When stepping through code (the links in the call stack should open the original source and displayName.In the console (the link to source should be the original file, not the generated one).When debugging your code and Source Maps enabled, Source Maps show in two places: You may also turn on the Enable CSS Source Maps.Д®nable JavaScript Source Maps Debugging with Source Maps On the Preferences pane, under Sources, turn on Enable JavaScript Source Maps. Source Maps are enabled by default, but if you want to double-check or enable them first open DevTools, choose Customize and control DevTools (. So in effect it gives you the illusion that you are running a dev site in production. Any errors, logs, and breakpoints map to the dev code for awesome debugging. Source Maps in DevTools is using source mapping, but the underlying functionality actually runs the compiled code. When running Source Maps in DevTools, you should notice that the JavaScript is not compiled and all of the individual JavaScript files it references are displayed. The running of the code gives you the illusion of running a development site in production. Meanwhile, Microsoft Edge is actually running your minified code. You then use the originals to set breakpoints and step through code. Source Maps from preprocessors cause DevTools to load your original files in addition to your minified ones. Compilers ( Closure Compiler, TypeScript, CoffeeScript, Dart).The following types of preprocessors are commonly used in combination with Source Maps: For an extended view, navigate to Source maps: languages, tools and other info wiki page. Use a minifier that is capable of creating source maps.

This article explains how to interact with JavaScript Source Maps in the DevTools Sources tool. Verify that your web server is able to serve Source Maps.Only use pre-processors capable of producing Source Maps.You are then able to read and debug compiled code in the original source. Use Source Maps to map minified code to source code.Use source maps to map your source code to your compiled code. Keep your client-side code readable and debuggable even after you combine, minify, or compile it.
