Node | Require is not defined [duplicate]

问题

Edit : Problem solved using webpack

For the needs of an API, I needed to import MD5 and moment. I downloaded the packages using the basic npm install but when I try to import it on my app.js using the code below :

const md5 = require ('./node_modules/md5/md5.js');
const moment = require ('./node_modules/moment/moment.js');

function getTimeStamp () {
    return moment.utc ().format ('YYYYMMDDHHmmss');
}
let timestamp = getTimeStamp ();

function generateSignature (devId, method, authKey, timestamp) {
    return md5 (`${devId}${method}${apiKey}${timestamp}`);
}
let signature = generateSignature (XXXX, "createsession", "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX", getTimeStamp ());

I get this message in the console :

Uncaught ReferenceError: require is not defined

I don't know what I'm doing wrong because I used the same method for another program and it worked perfectly...

Thanks in advance

You're probably seeing this error because require() does not exist in the browser/client-side JavaScript. If you want to use require() in the browser, then you need to use something like require.js

RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node.

PS: I agree with cptwonton. Please refer to the mentioned post for an in-depth solution with the various options available.

try this:

const md5 = require ("md5");
const moment = require ("moment");

回答3:

require isn't supported in a browser because Node and ES6 have their different module systems. Are you trying to call require in a browser? In that case I suggest you to setup Babel. But if you use node, then try reistalling nodejs.
