Basically I created an Ionic v4 blank application and import Zlib library: import { Component } from '@angular/core'; imports * as zlib from 'zlib'; import { Buffer } from 'buffer'; @Component({ selects: 'app-home', templateUrl: 'home.page.html', styleUrls: ['home.page.scss'], }) export class HomePage { constructor() { test_zlib(); } test_zlib() { constant input = '..................'; zlib.deflate(input, function(err, buffer) { if (!err) { console.log(buffer.toString('base64')); } } } Running the example using the nodejs console is ok, but runs ionic serve, navigator triggers an error that shows: core.js:9110 ERROR Error: Uncaught (in promise): ReferenceError: Buffer is not defined ReferenceError: Buffer is not defined on Object.../node_modules/core-util-is/lib/util.js (util.js:103) on __we Would you please check it and let me know what I'm doing wrong? Sergiosmail: Let me know what I'm doing wrong? Welcome! Since this is your first post here, maybe you're not familiar with my general disdain for the whole world of JavaScript, but here's one more thing to hate: there are plenty of libraries that expect to run under Node.js, and don't deal really well with life in a browser. You seem to have stumbled upon one of these. I would look for a replacement that advertises browser support: maybe this one? I already work with Pako library, thanks for the tips @rapropos. Somewhere I did see that javascript was hatest and lovest programming language, I'm starting to understand why. Referring to zlib it though, why are you so sure that LIB doesn't work with browser? I don't want to invest a whole day next time I can't turn the work into a music library in the browser. sergiosmail: Somewhere I did see that javascript was hatest and lovest programming language, I'm starting to understand why. Ironically, pretty much the only thing I like about it - the fact that it's easy to implement interpreters for it - is very much the reason why I have to deal with the gigantic mountain of things I hate about it because it's so universal. sergiosmail: Referring to zlib it yourself, why are you so sure that LIB does not work with browser? I guess it's not really zlib itself, but that implementation you're working with. My mental checklist for can this be a node/browser concern? goes something like this: are we dealing with a headless library that primarily deals with munging data on, instead of doing something visual? if so, increase the likelihood we are seeing uncaught exceptions that spawn right inside without app code involved at all (yes, in your case)? if this is the case, increase the likelihood of them involving undefined identifiers, in particular of the usual suspects in these cases like buffer, fs or crypto? if so, increase the probability look at the project documentation and error list - is it supposed to work in the browser? if so, lower probability. are people using it a browser environment? if so, lower probability is people trying to use it in a browser environment, right, and archiving bugs? if so, increase the probability greatly did the OP try to run this library under the node and had no problems? (OK, it's never happened before, but you did it, which was a huge help to me), if so, increase the likelihood through the roof Understood! Very clear and helpful to me Hello, In the following number: there is comment on how to find out where the Buffer constructor is used: you can easily drop a break point on the error in your browser's inspector and then refresh the page to hit the breakpoint and see via the call stack which package is trying to use Buffer. Could any body help how to drop a breakpoint? Greetings, Mirlan Click to link just below errors, smth like this modules.js?hash = 282a9f8.. b8702a In my case, it's helpers.js from meteor-node-stubs Thank you. It helps.js in my case too. Tried to add global. Buffer = Global. Buffer || (buffer). Buffer;inside <app_path>i /client/lib/init.js but without success. I know (-: I tried too. And without success too (-: Solved. By puttin global. Buffer = Global. Buffer || (buffer). Buffer; <app_path>to /client/lib/init.js. My bad, I tried by putting it in some different folder inside <app_path>/ client/. But it is resolved that it should be put exactly in <app_path>/ client / lib / init.js. 5 Likes same for me (-: Very strange (-: Adding an init.js file in my client folder with this particular line fixed my broken app. Thanks!
