ESLint 8 removed CLIEngine. Therefore, we need to migrate away from CLIEngine to the main ESLint class (which already exists in ESLint 7). However, that class is based on promises, which means we can't use them in a CommonJS context. Therefore, introduce a new `.mjs` version that uses ES modules (which can do as we are on a recent version of Node) and use the promise versions. There are no other functional changes compared to the old `.js` script. The reason that we first have to add this file here, is that our CQ directly refers to the `.js` version. That means we first land this CL, we update our CQ configuration and only then can we remove the `.js` file from our repository.

DevTools Scripts
Development workflow scripts
These are scripts that can be useful to run independently as you're working on Chrome DevTools front-end.
The newer scripts such as for testing and hosted mode are written in Node.js, which has become the standard toolchain for web apps. The older scripts such as building (e.g. bundling and minifying) are written in Python, which has first-class support in Chromium's infrastructure.
Overview
Folders
- build - Python package for generating DevTools debug and release mode
- chrome_debug_launcher - automagically finds Chrome Canary and launches it with debugging flags (e.g. remote debugging port)
- closure - see section on Closure Compiler below
- gulp - experimental build process written in node.js & gulp to remove the dependency on Chromium-specific build tools (i.e. gn and ninja)
- hosted_mode - run DevTools on a localhost development server
Python Scripts
- compile_frontend.py - runs closure compiler to do static type analysis
- Note: the compiled outputs are not actually used to run DevTools
- lint_javascript.py - run eslint
Node.js scripts
The easiest way to run the node.js scripts is to use npm run which displays all the commands. For more information on the specific npm run commands, take a look at the primary devtools front-end readme (../readme.md).
