Kibana and X-Pack are very large TypeScript projects, and it comes at a cost. Editor responsiveness is not great, and the CLI type check for X-Pack takes about a minute. To get faster feedback, we create a smaller APM TypeScript project that only type checks the APM project and the files it uses. This optimization consists of modifying `tsconfig.json` in the X-Pack folder to only include APM files, and editing the Kibana configuration to not include any files. The script configures git to ignore any changes in these files, and has an undo script as well.
