waitnrun

wait-and-run

Starts server, waits for URL, then run your tests.

This package is developed because I could not resolve npm audit issues of "start-and-server" package, especially wait-on and axios package.

It's a simplified version of start-server-and-test. It has zero dependency. Therefore, you will see 0(zero) security vulnerability.

The package size is 2.3KB(0 npm module dependency), compared to start-server-and-test's 11KB(plus 107 npm module dependencies).

Install

Requires Node version 16 or above.

npm install waitnrun -D

Usage

const procs = await waitnrun(['http-server', ':8080', 'ng serve', ':3000', 'cypress run']);
procs.forEach(proc => proc?.kill?.());

CLI

# run http-server, then when port 8000 responds run Cypress tests
waitnrun 'npx http-server' 8080 'cypress run'
waitnrun 'npx http-server' :8080/index.html 'cypress run'
waitnrun 'npx http-server' http://localhost:8080/index.html 'cypress run'
waitnrun start-server :4300/api/health 'ng serve' 'cypress run'
