Using jsonld.js in Node-RED (with browserify)

[KMax]

I use the library as a part of my .js file which is compiled with browserify. The input file for browserify is below and the output file is called bundle.js:

"use strict";

... // other imports via require(...);
global.JSONLD = require('jsonld');

When I import bundle.js in .html file which is a part of any Node-RED plugin and do console.log(JSONLD);, in the console I see an empty object, i.e. Object {}. But if I import the file in a plain HTML outside of Node-RED environment, the library works correctly, i.e. it's imported as a function.

Other libraries which I import in the same way, in example N3.js and axios, work correctly in both cases.

It's just my guess, but probably the issue is in the way the library is exported.

I found a workaround which unfortunately requires to make small changes in the source code of jsonld.js.

• comment out lines 8060 - 8079
• add var factory = wrapper({}); before line 8080
• comment out lines 8081 - 8091

After these changes, import the library with ... = require('./jsonld.js'); and the code will work in the both cases mentioned earlier.

I stumbled upon the same issue and patch proposed in previous comment solved it.

@nopnop I remember that you fixed browserify compatibility before in #56, could you imagine taking a look at this issue?

Hi @elf-pavlik,

Sorry for the late answer (I've seen your notification but I should have been distracted at the time).
I've pushed a PR that is, maybe, an acceptable solution to the browserify support issues.

Closing as very old and the landscape has changed -- or this may now potentially duplicate #399 in some way.
