Overview

When you enable the enablePrivacyForActionName initialization parameter, action names are masked for privacy. In minified builds, action names can also become unreadable because bundlers obfuscate the DOM element text and attributes that RUM uses to generate action names.

The Action Name Deobfuscation build plugin addresses both issues by instrumenting your source code at build time to generate a privacy dictionary that maps obfuscated values back to their original text. The RUM SDK uses this dictionary to resolve readable action names.

Prerequisites

The RUM SDK initialized with trackUserInteractions: true and enablePrivacyForActionName: true. See Mask all action names.
The Datadog build plugin installed and registered with your bundler. See Build Plugins for installation instructions.

Configuration

Configure the rum.privacy object in your build plugin options:

Parameter	Type	Required	Default	Description
`rum.privacy.include`	Array of RegExp or String	No	JS/TS files (.js, .ts, .jsx, .tsx, .mjs, .cjs, and variants)	File patterns to process for action name deobfuscation.
`rum.privacy.exclude`	Array of RegExp or String	No	`node_modules`, `.preval.` files	File patterns to skip.

Example

With default settings (processes all JS/TS files, excludes node_modules):

const { datadogWebpackPlugin } = require('@datadog/webpack-plugin');

module.exports = {
  plugins: [
    datadogWebpackPlugin({
      rum: {
        privacy: {},
      },
    }),
  ],
};

With custom include and exclude patterns:

const { datadogWebpackPlugin } = require('@datadog/webpack-plugin');

module.exports = {
  plugins: [
    datadogWebpackPlugin({
      rum: {
        privacy: {
          include: [/\.jsx?$/, /\.tsx?$/],
          exclude: [/\/node_modules\//, /\/test\//],
        },
      },
    }),
  ],
};
