This is a short guide on how to use absolute imports in React Native.
Absolute imports
The absolute imports are a feature that was introduced in ES2020. It allows you to import modules using an absolute path instead of a relative path.
For example, if you have a file called App.js
in the src
folder, you can import a module called utils.js
using the following code:
import { sum } from 'src/utils';
This is a simple example, but it can be very useful when you have a complex project with many files and folders.
How to use absolute imports in React Native
To use absolute imports in React Native, you need to install the babel-plugin-module-resolver
package.
yarn add -D babel-plugin-module-resolver
After installing the package, you need to configure it in the babel.config.js
file.
module.exports = {
presets: ['babel-preset-expo'],
plugins: [
[
'module-resolver',
{
root: ['./src'],
alias: {
'~/assets': './src/assets',
'~/contexts': './src/contexts',
'~/screens': './src/screens',
'~/styles': './src/styles',
'~/routes': './src/routes',
'~/services': './src/services',
'~/hooks': './src/hooks',
'~/shared': './src/shared',
},
},
],
],
};
The root
property is used to define the root folder of the project. In this case, it is the src
folder.
The alias
property is used to define the aliases that will be used in the imports. In this case, I defined the following aliases:
-
~/assets
:./src/assets
-
~/contexts
:./src/contexts
-
~/screens
:./src/screens
…
The aliases are used to import modules using the ~
character. For example, if you want to import the App.js
file in the screens
folder, you can use the following code:
import App from '~/screens/App';
If you are using Typescript, you will need to add the following code to the tsconfig.json
file:
{
"compilerOptions": {
"baseUrl": "./src",
"paths": {
"~/*": ["*"]
}
}
}
It is important to note that the baseUrl
property must be the same as the root
property in the babel.config.js
file.
Now you will be able to use absolute imports in your React Native project.

~/screens/Home could not be found within the project or in these directories:
didn't work in typescript
Without code, I can't help you. Did you follow all the steps above?
