How to run node.js app multiple times with different arguments in command line

Question

I need to start node.js app multiple times (200-300 times) with different arguments. Like so:

node index.js ABC
node index.js DEF
...
node index.js XYZ

What is the best approach to achieve that?

Answer 1

1. put all your arguments line by line in params.txt :

   ABC

   DEF

   GHI

   ...

   XYZ

2. RUN cat params.txt | while read -r param; do node index.js $param; done

The script above read the file line by line and pass it to your js script
