Repro steps

• ng new jszip-test
• cd .\jszip-test\
• npm i --save jszip
• Add the following code in app.component.ts:

import * as JSZip from 'jszip';
...
constructor() {
    const zip = new JSZip();
}

• ng build

Observed behavior

ERROR in ./node_modules/jszip/lib/readable-stream-browser.js
Module not found: Error: Can't resolve 'stream' in 'C:\dev\jszip-test\node_modules\jszip\lib'

Desired behavior

Should be able to build a project without errors.

Mention any other details that might be useful (optional)

This works as expected with angular-cli 1.7

[kodermax]

I have the same error.

[ps-arndwestermann]

Same for me. :s

[051181]

Same for me

[Walgermo]

Same 👎

[kodermax]

My short fix:
node_modules/jszip/lib/readable-stream-browser.js

module.exports = require("readable-stream");

[ps-arndwestermann]

Worked for me as well, thank you! :)

[frohrka]

I have the same error message with ng serve.

[jtsom]

Same here as @frohrka . But I don't specifically have jszip in my package.json

[ps-arndwestermann]

I had the same problem as @frohrka, but i tried the solution from @kodermax and it worked for me. Just give it a try. ^^

[jtsom]

Yes, that did work, but seems to be a hacky workaround....Next time the packages are updated/reloaded, will have to do that again. Not ideal.

[clydin]

Please see the following comment: #9827 (comment)

Duplicate of #9827

[sachinpachori]

@kodermax How this can be fixed when you are running the build from the build pipeline?
How will you modify to add the following in node_modules/jszip/lib/readable-stream-browser.js in the build pipeline as the node modules are installed on the fly:
module.exports = require("readable-stream");

[clydin]

@sachinpachori Please see this comment: #9827 (comment)

[kodermax]

It was hot fix.
Right fix:
tsconfig.json

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "paths": {
      "jszip": [
        "../node_modules/jszip/dist/jszip.js"
      ]
    },
    "lib": [
      "es2017",
      "dom"
    ]
  }
}

[sachinpachori]

I tried it with and without 2 dots before node_modules in the path....still getting the error: Module not found: Error: Can't resolve 'stream' in 'D:\a\1\s\node_modules\jszip\lib'

[sachinpachori]

ERROR in ./node_modules/jszip/lib/readable-stream-browser.js�[39m�[22m�[0m

[clydin]

Correct solution is in the comment linked above.

[sachinpachori]

@clydin If you are mentioning about your comment on Mar 2 then that is what I tried and still facing the error mentioned above.

[ztimson]

@sachinpachori I added this to my package.json file

"scripts": {
    ...
    "fix": "echo \"module.exports = require('readable-stream');\" > ./node_modules/jszip/lib/readable-stream-browser.js",
    ...
}

Than in your build script:

npm install
npm run fix
ng build // Or what ever you use

Not ideal but it works

[sachinpachori]

Thanks @ztimson. I created a custom npm task in build definition and put the command "npm run fix" there and getting the error:

What am I doing wrong here?

[sachinpachori]

[clydin]

That solution is confirmed to work. Ensure it is placed in the application's tsconfig not the root tsconfig. Also ensure the path (relative to the baseUrl) matches the project structure. If that error is shown, the path mapping is either not being used or the file is not being found. The files in dist of the jszip package are bundled and self-contained. They will not request other files within the package.

[ztimson]

@sachinpachori I am not sure why, but the error is that it doesn't recognize the command npm run

Can you show me the package.json line where you put the command?

[sachinpachori]

that is what I was wondering too :)

[sachinpachori]

@clydin Earlier I put it in the root one and now I tried it with app tsconfig but it fails with the same error.

[ztimson]

@sachinpachori if you look at my snippit again I escaped the quotes with a backslash. Your code isn't escaping them.

[sachinpachori]

@ztimson It is missed while pasting but I checked it is there in the checked in code and not working. Do I need to use your solution in addition to what clydin suggested or need to use yours only? Moreover," npm run" is not recognized and it shall not be related to the escape character I guess. Do you have a working build definition which you can share?

[sachinpachori]

It is fixed now. Thanks @ztimson your fix worked. Issue was in build definition.

[SpiraMira]

Thanks @ztimson your fix worked like a charm!

[aifrim]

npm i stream - worked for me

[ztimson]

@aifrim Worked for me

[nhustak]

@aifrim npm i stream also worked fo rme

[apeter10]

@aifrim Worked for me

[baree2008]

@aifrim work for me.

[cesarochoa2006]

@aifrim npm i stream also worked fo rme

This is the true solution. All the answers before trigger workarounds, but no solutions

[tmtron]

Please see the following comment: #9827 (comment)

Duplicate of #9827

this solution causes other issues - see Stackoverflow: typescript does not find jszip types

So the better option, in my opinion, is to install the stream package

npm i stream

as answered by @aifrim comment-link

[Zymex]

npm i stream - worked for me

This just worked for me with Angular 8. Angular Templates & ASP.NET Core don't seem to play nicely. This is the true fix, everything else is work-around.

[AkashKumarKhatri]

Angular 7

ERROR in ./node_modules/jszip/lib/readable-stream-browser.js
Module not found: Error: Can't resolve 'stream' in 'D:\MIMS\MIMS_Angular\node_modules\jszip\lib'

I am facing this issue in my application after added.

DevExtreme

Then after some searching, I found this solution.

I Just replace:
module.exports = require("stream");
With:
module.exports = require("readable-stream");

In readable-stream-browser.js

It perfectly works for me, I don't recommend you to go for this approach it is one the approach that is a good solution.

Thanks! Happy Coding
