I am new to monorepo.
The thing is they want me to upload a sourcemap to the rollbar.
But I don't know how to generate one.
When I ask for help they told me to read documents. I read the documents / watch Youtube videos for long time but i am still not clear about generating the source map.
In our monorepo we got lots of project
apps
- ProjectA
- ProjectB
- ProjectC
- ProjectD
The thing is i want to generate source map for the ProjectC.
To generate the source map I think i need to build the project ( tell me if i am wrong )
so I look into the project.json. But I don't see the build command.
{
"$schema": "../../node_modules/nx/schemas/project-schema.json",
"sourceRoot": "apps/ProjectC",
"projectType": "application",
"targets": {
"lint": {
"executor": "#nrwl/linter:eslint",
"outputs": ["{options.outputFile}"],
"options": {
"lintFilePatterns": ["apps/ProjectC/src/**/*.ts"]
}
},
"test": {
"executor": "#nrwl/jest:jest",
"outputs": ["coverage/apps/ProjectC"],
"options": {
"jestConfig": "apps/ProjectC/jest.config.ts",
"passWithNoTests": true
}
}
},
"tags": []
}
How can i configure so that it will produce a sourcemap file? ProjectC is a vue app.
The thing is in the tsconfig.app.json. I see the configuration like this. But I don't find the source map. Is this file related to generating source map?

"compilerOptions": {

I'm trying to configure jest/babel to do react component testing in my app. So far I'm facing some difficulties, in imports.
It throws this error:
Here is my babel.config.json:
{
"plugins": [
"#babel/plugin-proposal-class-properties",
"#babel/plugin-transform-runtime"
],
"presets": [
[
"#babel/preset-env",
{
"targets": {
"node": "current"
}
}
],
"#babel/preset-react"
]
}
I've trying adding "type": "module" in the package.json and it brings different problems upon itself. I would appreciate any help!
I have a app that created by react-native init command.
My app import websocket package which in turn require http package and cause error said "Unable to resolve module http".
i.e: myApp -> 3rd-module -> ws -> http
I try to work-around by install "#tradle/react-native-http", and added follow lines to my app's package json file:
"browser": { "http": "#tradle/react-native-http" },
"react-native": { "http": "#tradle/react-native-http" },
but it doesn't work.
I also try using babel-plugin-module-resolver but unluck either. Here is my .babelrc :
{
"presets": ["module:metro-react-native-babel-preset"],
"plugins": [
[
"#babel/plugin-proposal-decorators",
{
"legacy": true
}
],
["module-resolver", {
"alias": {
"#tradle/react-native-http": "http"
}
}]
]
}
How to do alias for my case? I research to fixing this problem by using webpack configuration, but don't know where is the configure file. After google, i think project created by react-native init use metro config instead of webpack.
try
["module-resolver", {
"alias": {
"http":"#tradle/react-native-http"
}
}]
After upgrading to react-native 0.56 I'm experiencing tons of babel reated errors on jest specs that used to run just fine.
I realize that react-native 0.56 requires babel7 and that's probably related but I don't have enough experience/understaanding in babel to figure out what I'm missing.
Some error examples:
/xxx/spec/Bootstrap.test.js:6
import thunk from 'redux-thunk';
^^^^^

My package.json jest config is as follows:

"coverageDirectory": "coverage",

},
.babelrc is defined as follows:
{
"presets": ["react-native"],
"env": {
"development": {
"plugins": ["transform-class-properties"]
},
"test": {
"plugins": ["transform-class-properties"]

}
}
I also have the following devdependencies:
"#babel/core": "^7.0.0-beta.52",
"babel-core": "^7.0.0-beta.52",
"babel-eslint": "~8.2.5",
"babel-plugin-module-resolver": "^3.1.1",

"babel-preset-react-native": "^5.0.1",
"babel-preset-react-native-stage-0": "^1.0.1",
"babel-preset-stage-0": "^6.24.1",
I've tried several approaches but couldn't progress much.
Besides the jest environment, the application runs fine.
Details of the workaround I did to move on, while 0.57 wasn't ready:
Basically I had to create 2 config files:
jest-acceptance.config (with the following relevant snippets)
"preset": "react-native",
"transform": {
"^.+\\.js$": "<rootDir>/custom_b7_processor.js"
},
"testRegex": "(/test/.*|(\\.|/)spec)\\.js$",
jest-unit.config (with the following relevant snippets)
"preset": "react-native",
"testRegex": "(/test/.*|(\\.|/)test)\\.js$",
That custom_b7_processor, is some sort of internal code from react-native:

At my .babelrc I had to include the following:
"presets": ["./node_modules/babel-preset-react-native-b6"],
That is pointing to a fork I made of the babel preset that React-native was using at 0.56-
https://github.com/lhrolim/babel-preset-react-native.
At my package.json I had te following babel dependencies
"babel-preset-react-native": "~5.0.2",
"babel-preset-react-native-b6": "github:lhrolim/babel-preset-react-native",
The test scripts I used then:
"test": "npm run test-acc && npm run test-unit",
"test-acc": "jest --config=jest_acceptance-config.json",
"test-unit": "jest --config=jest_unit-config.json",
I believe there might be some redundancies here and there, but that's what worked for me.
I have installed eslint in my machine and i have used visual studio code
i have certain modules and process to be exported
When i try to use "module" or "process" it shows
it was working fine before.
[eslint] 'module' is not defined. (no-undef)
[eslint] 'process' is not defined. (no-undef)
and here is my .eslintrc.json
{
"env": {
"browser": true,
"amd": true
},
"parserOptions": {
"ecmaVersion": 6
},
"extends": "eslint:recommended",
"rules": {
"no-console": "off",
"indent": [
"error",
"tab"
],
"linebreak-style": [
"error",
"windows"
],
"quotes": [
"error",
"single"
],
"semi": [
"error",
"always"
]
}
}
I want to remove this error
You are probably trying to run this in node environment.
The env section should look like this:
"env": {
"browser": true,
"amd": true,
"node": true
},
In your ESLint config file, simply add this:
{
...
env: {
node: true
}
...
}
That should fix the "module" is not defined and "process" is not defined error.
That assumes you are running in a Node environment. There is also the browser option for a browser environment. You can apply both based on your need.
If you want to prevent ESLint from linting some globals then you will need to add the specific global variables in the globals section of the config.
globals: {
window: true,
module: true
}
You need to tell eslint that you are in a Node environment. My favourite way to do this for one-off files like gulpfile.js is to include this comment at the top:
/* eslint-env node */
I think you can just rename all your CommonJS config files to have .cjs as their extension and then add this to eslintrc.cjs:
module.exports = {
// ...
env: {
// If you don't want to change this to `node: true` globally
es2022: true,
},
// then add this:
overrides: [
{
files: ['**/*.cjs'],
env: {
node: true,
},
},
],
}
