How can I add the CopyWebpackPlugin to create-react-app without ejecting?
It is definitely not recommended to modify the node_modules/react-scripts/config/webpack.config.dev.js
file as this will break when this particular package is updated. Also most probably you would be having node_modules
ignored in your version control system, meaning this config wont be shared across developers or backed up.
Although I haven't tried myself personally you could use something like this : https://github.com/timarney/react-app-rewired to override the Webpack config.
You can have a look at the tutorial here : https://medium.com/@timarney/but-i-dont-wanna-eject-3e3da5826e39
Assuming you just want to move files from -/src/<somewhere>
to ./<somewhereElse>
at build time.
You could just add an extra step to your build
script in package.json. The step below is completely in your control and does not mess with any create-react-app scripts or configuration.
For example, I used the ncp
package, but if you want more granular control, you can also create your own "step" with ncp or even with raw node fs api.
Here is a way to replicate what I did:
Setup
npx create-react-app img-upload
cd img-upload/
yarn add --dev ncp
Test Data create src/images/ folder structure and put in files
ls -R src/images/
src/images/:
badge.jpg folder1
src/images/folder1:
applause.gif blank.png
Package.json
I only edited the part: "build": "ncp './src/images' './public/images' && react-scripts build",
{
"name": "img-upload",
"version": "0.1.0",
"private": true,
"dependencies": {
"react": "^16.4.2",
"react-dom": "^16.4.2",
"react-scripts": "1.1.5"
},
"scripts": {
"start": "react-scripts start",
"build": "ncp './src/images' './public/images' && react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
},
"devDependencies": {
"ncp": "^2.0.0"
}
}
Test: Before running build:
ls public
favicon.ico index.html manifest.json
After running build: yarn build
ls public
favicon.ico images index.html manifest.json
ls -R public/images
public/images/:
badge.jpg folder1
public/images/folder1:
applause.gif blank.png
ls build
asset-manifest.json favicon.ico images index.html manifest.json service-worker.js static
ls -R build/images
build/images/:
badge.jpg folder1
build/images/folder1:
applause.gif blank.png
Suggestion
I am assuming you ultimately need these files in build
directory. If so, you can just switch your build
script.
"build": "react-scripts build && ncp './src/images' './build/images'",
That way you won't pollute your public folder, which you may want to keep in your source control.
