How to pass argument to Mongo Script

Question

I\'ve been using mongo and script files like this:

$ mongo getSimilar.js

I would like to pass an argument to the file:

$ mo         


        

Answer 1

I solved this problem, by using the javascript bundler parcel: https://parceljs.org/

With this, one can use node environment variables in a script like:

var collection = process.env.COLLECTION;

when building with parcel, the env var gets inlined:

parcel build ./src/index.js --no-source-maps

The only downside is, that you have to rebuild the script every time you want to change the env vars. But since parcel is really fast, this is not really a problem imho.
