Source Maps & Debugging
In this tutorial, we'll learn about source maps, which help make debugging your TypeScript code much easier. We'll also explore how to configure source map options in the
What are Source Maps?
Generating Source Maps
To generate source maps, you need to enable the
sourceMap option in your
tsconfig.json file. Set it to
When the TypeScript compiler compiles your code, it will generate a
.js.map file for each
.ts file. These map files will be used by your browser's developer tools to display the original TypeScript code during debugging.
Inline Source Maps
Instead of generating separate
To enable inline source maps, set the
inlineSourceMap option to
true in your
Note that you should not enable both
inlineSourceMap at the same time, as they are mutually exclusive.
Including TypeScript Source Code
By default, source maps only include the file names and line numbers of the original TypeScript code. If you want to include the actual TypeScript source code in the source maps, enable the inlineSources option:
This will embed your TypeScript code directly in the
In this tutorial, we've explored source maps and their usefulness in debugging TypeScript code. By configuring the
tsconfig.json file, you can generate and customize source maps to fit your debugging needs.
