Next.js auth with Github

Components and decorators for using Github authentication with Next.js

Usage

1. Install into your Next.js app

   yarn add next-github-auth

2. Create sign-in and sign-out pages

   At pages/sign-in.js

   import { SignIn } from 'next-github-auth'
   export default SignIn

   At pages/sign-out.js

   import { SignOut } from 'next-github-auth'
   export default SignOut

   If you need to customize the scope you can configure the SignIn page

   import { configureSignIn } from 'next-github-auth'
   const SignIn = configureSignIn({ scope: 'repo gist' })
   export default SignIn

3. Wrap private pages with PrivatePage decorator

   Any Next.js page that should only be accessible to authenticated users should be wrapped with the PrivatePage decorator, e.g.:

   import { PrivatePage } from 'next-github-auth'
   
   const Private = props => <div>private page!</div>
   export default PrivatePage(Private)

4. Wrap public pages with PublicPage decorator

   All other Next.js pages should be wrapped with the PublicPage decorator, e.g.:

   import { PublicPage } from 'next-github-auth'
   
   const Public = props => <div>public page!</div>
   export default PublicPage(Public)

5. Optionally access the currently signed in github user and access tokens in a Next page component's getInitialProps, e.g:

   import React from 'react'
   import PropTypes from 'prop-types'
   import { PrivatePage } from 'next-github-auth'
   
   const UserRepos = ({
     github: {
       accessToken,
       user: { login }
     }
   }) => (
     <div>
       {!repos.length && (
         <div>cool, you have 0 repos!</div>
       )}
   
       {!!repos.length && (
         <ul style={{ margin: 0 }}>
           {repos.map(({ fullName }) => (
             <li key={fullName}>{fullName}</li>
           ))}
         </ul>
       )}
     </div>
   )
   
   UserRepos.getInitialProps ({ github: { accessToken } }) {
     const githubRepos = await getGithubRepos(accessToken)
     const repos = githubRepos.map(repoView)
     return { repos }
   }
   
   export default PrivatePage(UserProfile)

6. Optionally access the currently signed in github user and access tokens via React's context, e.g:

   import React from 'react'
   import PropTypes from 'prop-types'
   import { PrivatePage } from 'next-github-auth'
   
   const UserProfile = (props, {
     github: {
       accessToken,
       user: { login }
     }
   }) => (
     <div>
       <div>{login}'s profile</div>
       <div>token: {accessToken ? 'hidden' : 'not available'}</div>
     </div>
   )
   
   UserProfile.contextTypes = {
     github: PropTypes.shape({
       accessToken: PropTypes.string,
       user: PropTypes.shape({
         login: PropTypes.string
       })
     })
   }
   
   export default PrivatePage(UserProfile)

Setup app environment

1. Add an OAuth application to your Github account to generate a client id and secret

   Set the callback URL to the public URL of the deployed app

2. Setup environment

   Export your GitHub app's client id and secret as environment variables

   export GITHUB_CLIENT_ID=YOUR_APP_ID
   export GITHUB_CLIENT_SECRET=YOUR_APP_SECRET

Run app

1. Start the app

   yarn dev
