Strange question, but currently I have a script that I run from the terminal which requires a parameter. Normally I will run this by doing node script.js param, but now I want to run this script with the parameter from inside a JS file when the Express server loads.
The parameter is taken in and defined in the file like this:
var param = process.argv[process.argv.length - 1];
What is the best practice for making this file accessible elsewhere in my Node app and running it?
If I understand you correctly following should work.
script.js
module.exports = function (params) {
console.log(params);
}
main.js
var param = process.argv[process.argv.length - 1];
require('./script')(param);
If you need to get param from another source when the script is required you can make a verification if the script is running directly from command line or it was required:
if (require.main === module) {
var param = process.argv[process.argv.length - 1];
} else {
var param = // get from other source.
}
require("script.js")file from other file?
