this is a follow-up to

however, you do not need to read that to understand the context here.

I have read and think I understand everything in this helpful but slightly difficult-to-find doc support.wix. com/en/article/velo-where-do-i-put-my-code

(when I say slightly difficult-to-find doc I mean currently it ranks Google #4 for the keyword “wix where do I put my code” even though you’d think this would be #1)

I am trying to use the NPM www.npmjs. com/package/branch-sdk to call a remote API via a backend call.

In my Main Pages, I have a file called simply example

this file is a blank page with this code


import {constructBranchURL} from "backend/constructBranchURL.jsw"
$w.onReady(function () {
 const branchResponse =  constructBranchURL().then((resp) => {
       console.log("branch is", resp)
 })
});

Under Code Files > Packages > NPM, I was able to successfully add the branch-sdk package

Now, the package branch-sdk appears installed under NMP in the sublist of Packages.

backend/constructBranchURL.jsw looks like so:

import branch from 'branch-sdk';
console.log("branch is", branch)

export function constructBranchURL() {
  console.log(" hello world ..." );
   branch.init('key_live_OUR_KEY_GOES_HERE', function(err, data) {
     console.log("callback")
 })
}

When I run this page, it looks like the backend has an error, which I can only see in Wix (not in the browser console) using Site Monitoring > Site Events

Looks like it just can’t load branch-sdk:

"jsonPayload":{

"message":"["Error loading web module backend/constructBranchURL.jsw: Cannot find module '/dynamic-modules/third-party-npm/facf9043/WC_BEGIN/branch-sdk/2.53.1/WC_END/branch-sdk/dist/build.min.js'. Please verify that the package.json has a valid \"main\" entry"]"
}

I believe the NPM package here is github. com/BranchMetrics/web-branch-deep-linking-attribution/blob/master/package.json , which does does seem to me to have a “main” entry.

Any tips on what to do next?

Also, are the packages I see in the Wix NPM “add NPM package” dashboard all approved? If so, I wonder why this seems to not load.

Are you sure this package is supposed to run on the backend and not only on the frontend?

from a front end file (‘example’)


import branch from 'branch-sdk' 
$w.onReady(function () {
    console.log(" hello world ..." );
   branch.init('key_live_OUR_KEY_GOES_HERE', function(err, data) {
     console.log("callback")
 })
});

gives me this in the console:

workerLogger.js:103 Cannot find module ‘branch-sdk’ in ‘public/pages/zkgug.js’

So I don’t know. Maybe something is wrong with the package.
