run-await-run

Run command, await response, run command

Inspired by start-server-and-test, just tiny compared!

Install

npm i -D run-await-run

Usage

Command to run NPM scripts in parallell, but second script waits for a response to begin. Usefull when first command starts up a server and second one should start afterwards.

run-await-run <run-first> <url> <run-second>

Example

{
  "scripts": {
    "server": "node ./server.js",
    "test": "run-await-run server :8080 'playwright test'"
  }
}

Options

position 1 (required): script one will run first
position 2 (required): URL waiting to respond
position 3 (required): script two will run when url responds
--get (optional): fetches the URL with a GET request. Default is a HEAD request
--timeout <number> (optional): when to stop waiting in milliseconds. Default is 300000 milliseconds (5 minutes)
--interval <number> (optional): how often to check if URL responds in milliseconds. Default is 100 milliseconds

Handy features

auto add npm run

If position 1 or 3 matches a script in package.json, it will automaticly add npm run. Meaning you can write e.g. server instead of 'npm run server'.

auto group arguments

Normally arguments must be wrapped by ", but groups argument by '. Meaning you can write 'npm run server' instead of \"npm run server\".

auto add localhost

If position 2 is just :<port>, it will add http://localhost:<port>/. Meaning you can write :8080 instead of http://localhost:8080/
