Get version number from package.json in React Redux (create-react-app)

Question

OP EDIT: If anyone else comes across this: the app was created using create-react-app, which limits importing to within the src folder. However if you upgrade react-scri

Answer 1

From your edit I would suggest to try

import packageJson from '/package.json';

You could also try to create a symlink:

# From the project root.
cd src; ln -s ../package.json package.alias.json

List contents of src directory and you'll see the symlink.

ls
#=> package.alias.json -> ../package.json

Adding the .alias helps reduce the magic for others and your future self when looking at this. Plus, it'll help text editors keep them apart. You'll thank me later. Just make sure you update your JS code to import from ./package.alias.json instead of ./package.json.

Also take a look at this question: The create-react-app imports restriction outside of src directory

Answer 2

I don't think getting version by 'import' or 'require' package is correct. You can add a script in you package.json

"start": "REACT_APP_VERSION=$npm_package_version react-app-script start",

You can get it by "process.env.REACT_APP_VERSION" in any js files.

It also works in build scripts, like this:

"build": "REACT_APP_VERSION=$npm_package_version react-app-script build",

Answer 3

Try this.

// in package.json
"version": "1.0.0"

// in index.js
import packageJson from '../package.json';
console.log(packageJson.version); // "1.0.0"

Answer 4

Solving this without importing and exposing package.json to the create-react-app

Requires: version 1.1.0+ of create-react-app

.env

REACT_APP_VERSION=$npm_package_version
REACT_APP_NAME=$npm_package_name

index.js

console.log(`${process.env.REACT_APP_NAME} ${process.env.REACT_APP_VERSION}`)

Note: the version (and many other npm config params) can be accessed

Note 2: changes to the .env file will be picked only after you restart the development server
