This script is a workaround for the issue with eslint integration in JetBrains IDEs and NX monorepo (or any other repository that has multiple eslint config files).

Details are described in this issue on JetBrains YouTrack.

Summary: jetbrains spawns multiple eslint processes that never die and consume a lot of memory especially when linting Typescript.

This scripts monitors memory consumption of eslint processes and kills them when they exceed max-memory down to optimal-process-count. Oldest inactive processes are killed first.

Script's goal is killing only eslint processes started by the IDE but there is a very unlikely chance that it may interfere with other eslint processes started by other utilities. (See how filtration works in the code)

Script is tested only on Linux. It should work on Windows and other platforms because used packages are cross-platform but it is not tested.

1. Checkout this repository
2. Run pnpm install or npm install
3. Run node main.mjs

Or you can install package globally:

pnpm install -g jetbrains-eslint-killer and then jetbrains-eslint-killer from any directory.

Try node main.mjs --max-memory=10 --interval=60 or node main.mjs --help for more options.

  -m, --max-memory             Maximum allowed memory consumption in GB. Exceeding this limit will lead to killings down to 'optimal-process-count'. Default: 6 GB
                                                      
  -c, --optimal-process-count  Number of eslint processes that should be left running if memory threshold is reached. Default: 2
                                                      
  -i, --interval               Check interval in seconds. Default: 30 seconds.
                                                      
  -s, --silent                 Don't output log messages. Default: false
