@replayio/sourcemap-upload

Provides an NPM library allows uploading sourcemaps to Replay's servers so that they can be used when viewing recordings.

Usage

This module will search the given filepaths for JS files and sourcemap files, and then it will use the file field of the sourcemap or the //# sourceMappingURL= comments in the JS to find pairs of sourcemap and JS file.

Debugging

If no sourcemaps are being found, consider running the function with verbose mode enabled, or with DEBUG=replay:sourcemap-upload set in the environment.

Most likely, if sourcemaps are not being found, they either:

• have no file property referencing their associated JS file
• the generated file has //# sourceMappingURL=

Either of these links is sufficient, so if changing the generated code to include a //# sourceMappingURL= comment is not what you want, including file is enough, and vice-versa.

API

This module exports a named uploadSourceMaps function with the following options:

interface Options {
  /**
   * The files/directories to search for sourcemaps. All files that match the
   * 'extensions' list and fail to match 'ignore' will be searched for
   * sourcemap JSON or `//#sourceMappingURL=` coments in order to find pairs
   * of generated-file + sourcemap, and the sourcemap will be uploaded.
   */
  filepaths: Array<string> | string;

  /**
   * To allow for tracking and browsing of maps that have been uploaded, we
   * require uploaded sourcemaps to have an overall group name associated with
   * them. This could for instance be a version number, or commit hash.
   */
  group: string;

  /**
   * The API key to use when connecting to Replay's servers.
   * Defaults to `process.env.REPLAY_API_KEY`.
   */
  key?: string;

  /**
   * Run all of the local processing and searching for maps, but skip uploading them.
   */
  dryRun?: boolean;

  /**
   * The set of file extensions to search for sourcemap-related data.
   * Defaults to [".js", ".map"].
   */
  extensions?: Array<string>;

  /**
   * The set of pattern for files to ignore when searching for sourcemap-related data.
   */
  ignore?: Array<string>;

  /**
   * Set the directory that relative paths should be computed with respect to.
   * The relative path of sourcemaps is included in the uploaded entry, and will be
   * visible in the UI, so this can be used to strip off unimportant directories in
   * the build path. Defaults to `process.cwd()`.
