Republic is a library for React that gives you universal routing, forms, and actions. It currently is built to work with Express + Next.js but has been built in mind that these may not always be the stack of choice.

If you miss the days of Rails forms and controllers, you'll love Republic.

Getting started

We have a lovely document for creating an application from scratch using Express + Next.js + Republic. The guide is a complete walkthrough that's ideal for first time users. Read it to get started.

Quick install

If you are familiar with Republic or you're just feeling brave you can use this quick start instead of the getting started guide. It's particularly ideal if you need a check list for adding Republic to your new application.

Set up Express + Next.js

Use Next.js's example of custom server using Express to setup your app ready to install Republic.

Defining your routes

Create an app.js file in the root of your application, or any where else, just remember to adjust the path when copying examples.

import Republic, { route } from 'republic/next'
export default new Republic('/blog', 'blog#index')

Defining your pages

Create a Next.js page in a directory that matches the action. For example with an action of 'blog#index' you should place your page in pages/blog/index.js.

You need to make sure you wrap your page with

import React from 'react'
import app from '../../app'
export default =>
    <h1>Hello world</h1>

That's your page setup.

Setting up republic

Install republic first with:

npm install --save republic

Now add two middleware to your Express setup. The following code adds parsing for POST data.

// Handle POST data 
import bodyParser from 'body-parser'
server.use(bodyParser.urlencoded({ extended: true }))

And then we add republic into the mix:

// Hook up upcoming + express + next 
import { asExpressMiddleware, nextHandler } from 'republic/express'
import app from './app'
server.use(asExpressMiddleware(app, nextHandler(nextApp)))

Make sure the path to your app file is correct.

Now you should be able to run the app and visit /blog or whatever your URL was.


To be completed...

new Republic






  • Form state handling
  • Connect form state to action handling
  • Form handling receives nested object rather than flattened string keys
  • Allow forms to have default state set
  • Pass actions in as functions rather than strings so they can be used with custom forms, and on other input events like click

Nice to haves:

  • Update route builders to accept middleware as arguments, array as single argument, or mix of both like Express
  • Pass rails-like params into handlers
  • Convention for express + next (helper wrappers)
  • Form error handling
  • Universal redirect
  • Abstract pages away from Next.js
  • Allow Form to have custom onSubmit
  • Provide all common form inputs
  • Upcoming middleware: how to, make sure API is easy to understand, etc.
