Module not found: Error: Can't resolve 'http' in 'C:\Users\BitsnIO-2\testapp\node_modules\json-schema-ref-parser\lib\resolvers'

When you say that you "compile it", I'm assuming you mean that you're using a bundler like WebPack, Rollup, Browserify, etc.? In that case, be sure that you're referencing the browser module (in the dist directory) rather than the Node.js module (in the lib directory). See the web browsers section in the ReadMe for details.

Thanks for the quick response and yes this will help i am sure.

Hi,

I'm getting the same error. I have an Ionic 4 project (Angular) and i installed this package with 'npm i json-schema-ref-parser'. I'm getting the following error if I run 'ionic build' (ng build).

ERROR in ./node_modules/json-schema-ref-parser/lib/resolvers/http.js Module not found: Error: Can't resolve 'http' in '.../node_modules/json-schema-ref-parser/lib/resolvers' ERROR in ./node_modules/json-schema-ref-parser/lib/resolvers/http.js Module not found: Error: Can't resolve 'https' in '.../node_modules/json-schema-ref-parser/lib/resolvers' [ERROR] An error occurred while running subprocess ng.

If i change the main property of the node_modules/json-schema-ref-parser/package.json from
"main": "lib/index.js", to
"main": "dist/ref-parser.js"
all is fine.

So, there might be a "package problem" but i should change things in the node_modules folder.
Where is the problem?

[JamesMessinger]

I assume that Ionic uses a bundler like Webpack or Rollup or something? If so, then there should be a way to specify module substitutions. The http module is a Node.js built-in, so it would need to be substituted with a browser polyfill, such as http-browserify. I know that in Rollup you can use rollup-plugin-node-builtins to do this automatically. In Webpack it requires a bit of configuration.

Hi,

under the hood, Ionic uses Angular 7 at the moment (for my project). I used json-schema-ref-parser with Ionic 3 (Angular 2/3) and it worked out of the box. So something changed...

The Angular CLI uses webpack (Version: webpack 4.28.4).
If I run ng build --verbose i get the following error (to narrow down the error):

I solved it by installing some npm browserify package and configure de tsconfig path option:

npm install http-browserify https-browserify stream-browserify

add this to tsconfig.js:

"paths": {

      //...

      "stream": [
        "node_modules/stream-browserify"
      ],
      "http": [
        "node_modules/http-browserify"
      ],
      "https": [
        "node_modules/https-browserify"
      ],

      //...

}

does this solution still a thing, using 10.1.0 apidevtools package doesn't seem having dist to reference it using webpack

also having same issues, ERROR in ./node_modules/swagger-parser/node_modules/@apidevtools/swagger-parser/lib/util.js 3:13-28
Module not found: Error: Can't resolve 'util' in 'C:\Repos\devportal-lmru-front\node_modules\swagger-parser\node_modules@apidevtools\swagger-parser\lib

Did you mean './util'?
