How to add node run option --max-http-header-size and add name to pm2 start command-CodePudding

How would I start a pm2 process with the —max-http-header-size node option, as well as name the process.

I have a server with multiple micro-services, one of the services is a web scraper.

This web scraper accepts requests with headers over the nodejs default 8kb limit. So, to run my app locally have to add the --max-http-header-size node option.

I've cloned my app to the server, but don't know how to set --max-http-header-size, nor do I know how to name the process within the pm2 start command.

So far my attempts have looked like this.

// this sets the name, but I don't know how to add the option `--max-http-header-size`
pm2 start npm --name "{REPONAME}" -- start

pm2 start node --name "scraper" --max-http-header-size 15000 app.js

pm2 start node --max-http-header-size 15000 app.js -- --name "scraper"

What you're looking for is called environment variables! You can pass environment variables to pm2 using a file that loads your server like this:

module.exports = {
  apps : [
      {
        name: "myapp",
        script: "./app.js",
        watch: true,
        env: {
          "max-http-header-size": "15000",
        }
      }
  ]
}
