Note

Valid source map files must meet the following requirements:

  1. Be available to Sealights Agent at the scanning (and instrumentation step) inside the workspace path

  2. The ‘sources’ section should refer to the right files from the source code maintained in the SCM

  3. The

relative
  1. relative path to the source files should be accurate and pointing to the right source folders

A common way for initial validation of the source map files is to open the application in a browser with the Developer mode and ensure the source code is properly retrieved and readable by the browser.

No Column Information

In the SeaLights Cockpit, you may see warnings about Detected source-maps without column information. Source maps information might be incorrect and may result in inaccurate coverage

...

In order to calculate the correct coverage, Sealights require the column information on top of the line information. in order to achieve that, please make sure you have set the following, depending on your build tool:

Webpack

Set In your webpack.config.js configuration file, set the devtool property to devtool: ‘source-map' or devtool: ‘inline-source-map'.
If you don’t want to change your project configuration, the corresponding webpack-cli commands will be --devtool 'source-map' or --devtool : 'inline-source-map'.

More details are available as part of the official Webpack documentation: https://webpack.js.org/configuration/devtool/ or https://webpack.js.org/api/cli/#flags

Typescript (tsc)

Add the relevant compiler option --sourceMap or --inlineSourceMap to the command line or to your tsconfig.json
