How do I access libraries I'm adding via require, in my Node/Koa server

Question

I'm trying to require an external library in my Node app (Koa server). I'm adding njwt in my main server.js file var njwt = require('njwt');

But I can't access njwt, in my route handler function it gives an error saying njwt is undefined.

From this answer (https://stackoverflow.com/a/5809968), it seems that using strict mode in my main server.js file makes functions and variables defined in my imported file inaccessible.

But what's the workaround?

Is the module installed in your local project? – Jack Ryan Nov 21 '17 at 06:13 — Jack Ryan, Nov 21 '17 at 06:13

If I am understanding correctly, all you need to do is change it to: var njwt = require('./njwt');

This is assuming you have already done an npm install in the njwt directory.

I think the issue is how to send njwt instance to your router, You can pass njwt instance like this,

require('./routes')(njwt);

I'm not sure if this is the best approach. I just ended up requiring the library in the route handler

const router = require('koa-router')();
router.post('/register', async function(ctx, next) {
    var jwt = require('jsonwebtoken');
    debugger;

And I'm able to access the library this way (the other two methods didn't work for me).
