joi-react-native

Note

• joi-react-native v3 uses joi 14.3.1 internally and works on react-native >= 0.59.0.

• joi-react-native v2 uses joi 14.1.0 internally and works on react-native < 0.58.0.

What is the difference between v3 and v2.

• Because react-native 0.59.0 has new JS Core, we don't need to use polyfills in v3 anymore. For this reason, file size in v3 is significantly smaller (50% smaller) and more performant compared to v2.

Install

npm i --save joi-react-native

Documentation

• There are no API changes from node Joi. Thus you can use the same documentation from here

https://github.com/hapijs/joi/blob/master/API.md

Works with TypeScript

Use babel plugin to transform all require/import from joi to joi-react-native. By doing this, you can use joi-react-native with type definitions from @types/joi.

1. Install babel-plugin-rewrite-require

   npm install --save-dev babel-plugin-rewrite-require

2. In .babelrc, add the following:

   "plugins": [
     ["rewrite-require", {
       aliases: {
         joi: 'joi-react-native',
       }
     }]
   ]

3. That's it. In any files that uses joi, you must require/import from joi (not joi-react-native). Babel will transform to joi-react-native for you
