Question 1

What are Source Map files?

Accepted Answer

Source map files (commonly with extensions like `.js.map` or `.css.map`) are files that map from the transformed source (e.g., minified JavaScript or compiled CSS) back to the original source code. This allows developers to debug their original code even when running the transformed version in the browser.

Question 2

What format are source map files usually in?

Accepted Answer

Source map files are typically in JSON format.

Question 3

How do I use the View Any File Source Map Viewer?

Accepted Answer

Click the "Open Local File" button to select a source map file (e.g., `script.js.map`) from your device. Its content will be displayed as plain text. You can also use our JSON Viewer (link to /viewer/json) for potentially better formatting if the file is indeed JSON.

Question 4

Does this tool interpret the source map?

Accepted Answer

No, this viewer only displays the text content of the source map file. It does not use the map to link to original source files or provide debugging capabilities. Browser developer tools use source maps for that purpose.
