My understanding is react-app-rewired no longer works in v2 of create-react-app.
It seems you need to get into babel (thus react-app-rewired).
You can use craco instead of react-app-rewired.
Information from react-app-rewired issue comments:
Here are some example craco.config.js configuration files:
Less
Ant Design + Less + modifyVars
Ant Design + Less + modifyVars + Preact
Preact
There are some more examples in the /recipes directory in the craco repo.
Example of craco.config.js from ndbroadbent:
const CracoAntDesignPlugin = require('craco-antd');
const { BundleAnalyzerPlugin } = require('webpack-bundle-analyzer');
const WebpackBar = require('webpackbar');
module.exports = {
webpack: {
alias: { react: 'preact-compat', 'react-dom': 'preact-compat' },
plugins: [
new BundleAnalyzerPlugin(),
new WebpackBar({ profile: true }),
],
},
plugins: [{ plugin: CracoAntDesignPlugin }],
};

Working first time on using Webpack in a ASP.Net Core project and running in to an issue bundling jQuery

I have tried and exhausted all possible variations I could find on the internet without any luck.
Using npm run build during the .Net build process to create the bundles
"$ is not defined" means that at the time when your library tried to do something with jQuery, jQuery itself either wasn't loaded or loaded incorrectly. Make sure that jQuery loads correctly first, and only then can the rest of the code use this library. Usually it is enough to put a jQuery call before all other calls.
My Vuejs App did not update after deployment for production, every time require "Empty cache and hard reload" to get the updates, I tried a lot of solutions to apply versioning to generated files after build but none of them worked for me, I need a solution to apply new hash for all files after every single build, not just the updated ones.
My vue.config.js file content:
const path = require("path");
module.exports = {
publicPath: process.env.NODE_ENV === "production" ? "/" : "/",
runtimeCompiler: true,
configureWebpack: {
resolve: {
alias: {
// If using the runtime only build
// vue$: "vue/dist/vue.runtime.esm.js" // 'vue/dist/vue.runtime.common.js' for webpack 1
// Or if using full build of Vue (runtime + compiler)
vue$: 'vue/dist/vue.esm.js', // 'vue/dist/vue.common.js' for webpack 1
'#': path.resolve('src'),
src: path.resolve('src'),
assets: path.resolve('src/assets'),
components: path.resolve('src/components'),
services: path.resolve('src/services'),
}
},
output: {
filename: '[name].[hash].js',
},
},
chainWebpack: config => {
config.module
.rule("eslint")
.use("eslint-loader")
.tap(options => {
options.configFile = path.resolve(__dirname, ".eslintrc.js");
return options;
});
},
};
Thanks in advance.
Welcome to the Vue JS cache nightmare. Did you try changing the version value in your package.json? I use to increment the value on each release as per x.y.z semantinc versioning. Maybe doing something like this:
{
"name": "My app",
"version": "1.0.15",
"private": true,
...
}
Storybook currently calls react-scripts. However, I've got some parts of the CRA config overriden with craco. It means my application is invoked with craco ..., rather than react-scripts ....
Is there a clean solution to have Storybook call craco instead?
The solution I came up with is this :
.storybook/main.js :
const path = require('path');
module.exports = {
stories: ['../src/**/*.stories.js'],
addons: [
'#storybook/preset-create-react-app',
'#storybook/addon-actions',
'#storybook/addon-links',
'#storybook/addon-viewport/register',
'#storybook/addon-knobs/register',
],
webpackFinal(config, { configType }) {
return {
...config,
resolve: {
alias: {
...config.resolve.alias,
'~': path.resolve(__dirname, '../src/'),
},
},
};
},
};
I was only using the alias feature in my craco file, so here I override webpack config from storybook and only add the alias parameter. For your case, you'll need to add your own config.
The #FR073N solution is good, but since the lasts versions, this throw an error.
One line was missing to fully override correctly the webpack config.
const path = require('path');
module.exports = {
stories: ['../src/**/*.stories.js'],
addons: [
'#storybook/preset-create-react-app',
'#storybook/addon-actions',
'#storybook/addon-links',
'#storybook/addon-viewport/register',
'#storybook/addon-knobs/register',
],
webpackFinal(config, { configType }) {
return {
...config,
resolve: {
...config.resolve, // <= HERE
alias: {
...config.resolve.alias,
'~': path.resolve(__dirname, '../src/'),
},
},
};
},
};
I've successfully used storybook-preset-craco with #storybook#6.3.5 and react-scripts#4.0.3 and #craco/craco#6.2.0 in a new CRA TypeScript project.
React native documentation state that
"You can also use this babel plugin that removes all the console.* calls. You need to install it first with npm i babel-plugin-transform-remove-console --save-dev, and then edit the .babelrc file under your project directory like this"
{
"env": {
"production": {
"plugins": ["transform-remove-console"]
}
}
}
I didn't find .babelrc file. Hence I made the following changes in babel.config.js file.
module.exports = {
presets: ['module:metro-react-native-babel-preset'],
env: {
production: {
plugins: ["transform-remove-console"]
}
}
};
But it's not working for me. The logs are displayed when I've tested them in Android Studio. What went wrong here?
The documented approach didn't work for my existing project either, but it worked in a new test project. I tried numerous dependency upgrades, adding/removing deps, plugins, etc. trying to figure out the source of the problem, but no luck. So finally I went with this workaround:
module.exports = {
plugins: ['#babel/plugin-proposal-numeric-separator', 'lodash'].concat(
process.env.NODE_ENV === 'production' ? ['transform-remove-console'] : []
),
presets: [
'module:metro-react-native-babel-preset',
['#babel/env', { targets: { node: 6 } }]
]
};
This should work (recommended method)
const presets = ['module:metro-react-native-babel-preset'];
const plugins = ['module:react-native-dotenv'];
if (process.env.ENV === 'prod') {
plugins.push('transform-remove-console');
}
module.exports = {presets, plugins};
Or if you don't want to use any package for this you can do this.
Place this in index.js
if(!__DEV__){
console.log = () => {}
}
I've noticed that there are virtually no info from babel on incorrect configuration. For example I've created new app with react-native-cli, installed decorators plugin and filled my babel.config.js as follows:
module.exports = {
presets: ['module:metro-react-native-babel-preset'],
plugins: ['#babel/plugin-proposal-decorators', { legacy: true }],
};
And there were the same complain as if no plugin is installed. Correct config would be:
module.exports = {
presets: ['module:metro-react-native-babel-preset'],
plugins: [['#babel/plugin-proposal-decorators', { legacy: true }]],
};
Now I'm trying to install jsx-control-statements and have the same silent fail causing
ReferenceError: Can't find variable: Choose as if no such plugin is installed at all. My babel.config.js is:
module.exports = {
presets: ['module:metro-react-native-babel-preset'],
plugins: [
'jsx-control-statements',
['#babel/plugin-proposal-decorators', { legacy: true }],
],
};
So the question is: How do I debug this configuration? How can I get some diagnostic from babel about incorrect configuration/not found packages etc.?
For instance if the presets/plugins are missing or missconfigured, you'll get an error when webpack takes over and try to load all the config. But I think your best shot is to use progressPlugin where you could display each step and see for yourself what is happening.
new webpack.ProgressPlugin((percentage, message, ...args) => {
console.log(percentage, message, ...args);
}),
Another approach, would be using debug module, as nearly all other plugins, modules use it.
DEBUG=* webpack [-c webpack.something.js]
Hope it helps
If you use babel.config.js you could do the following:
module.exports = function(api) {
if (api) {
api.cache(true);
api.debug = process.env.NODE_ENV === 'development' || false;
}
const presets = ['#babel/preset-env'];
const plugins = [
'#babel/plugin-proposal-class-properties',
...
];
return {
presets,
plugins,
};
};
