Exploring the variance between inlineSourceMap and inlineSources within the TypeScript compiler options

According to the documentation:

--inlineSourceMap and inlineSources command line options: --inlineSourceMap will include source map files within the generated .js files rather than in a separate .js.map file. --inlineSources allows for the source .ts file to be included within the .js file as well.

Does this mean that the entire source files are written to the outputFile? What is the benefit of doing this? After all, you can use the sourcemaps to recreate the original sources if needed.

Answer №1

It appears that by default, typescript sourcemaps will direct dev tools to the original source files rather than incorporating them into the sourcemaps themselves.

Without setting inlineSourceMap: true, you must provide the original .ts files alongside your bundled code.

Enabling inlineSourceMap: true changes this behavior to what one might expect from typescript: including the source information within the sourcemaps. This eliminates the need to serve the original source files along with the application bundle.
