Simple REST Data Provider for React Admin - Strapi

React Admin data provider for Strapi.js.

Usage

Save the index.js file as ra-strapi-rest.js and import it in your react-admin project. No need to npm install another dependency :)

import React from 'react';
import { fetchUtils, Admin, Resource } from 'react-admin';
import simpleRestProvider from './ra-strapi-rest';

IMPORTANT! Strapi Content-Range Header Setup

Make sure CORS is enabled in Strapi project
Add Content-Range to expose headers object <your_project>/config/environments/development/security.js

{
...
"cors": {
    "enabled": true,
    "origin": "*",
    "expose": [
      "WWW-Authenticate",
      "Server-Authorization",
      "Content-Range" // <<--- HERE
    ],
    ...
  },
  ...
}

In controllers, you need to set the Content-Range header with the total number of results to build the pagination

...
find: async (ctx) => {
  ctx.set('Content-Range', await <Model_Name>.count());
  if (ctx.query._q) {
    return strapi.services.<Model_Name>.search(ctx.query);
  } else {
    return strapi.services.<Model_Name>.fetchAll(ctx.query);
  }
},
...

Example:

...
find: async (ctx) => {
  ctx.set('Content-Range', await Post.count());
  if (ctx.query._q) {
    return strapi.services.post.search(ctx.query);
  } else {
    return strapi.services.post.fetchAll(ctx.query);
  }
},
...

Example

import React from 'react';
import { Admin, Resource } from 'react-admin';
import simpleRestProvider from './ra-strapi-rest';

import { PostList } from './posts';

const dataProvider = simpleRestProvider('http://localhost:1337');

const App = () => (
    <Admin dataProvider={dataProvider}>
        <Resource name="posts" list={PostList} />
    </Admin>
);

export default App;

Posts file:

import React from 'react';
import { List, Datagrid, TextField } from 'react-admin';

export const PostList = (props) => (
    <List {...props}>
        <Datagrid>
            <TextField source="id" />
            <TextField source="name" />
            <TextField source="description" />
        </Datagrid>
    </List>
);

Usage with AuthProvider

import React from 'react';
import { fetchUtils, Admin, Resource } from 'react-admin';
import simpleRestProvider from './ra-strapi-rest';
import authProvider from './authProvider'

import { PostList } from './posts';

const httpClient = (url, options = {}) => {
    if (!options.headers) {
        options.headers = new Headers({ Accept: 'application/json' });
    }
    const token = localStorage.getItem('token');
    options.headers.set('Authorization', `Bearer ${token}`);
    return fetchUtils.fetchJson(url, options);
}

const dataProvider = simpleRestProvider('http://localhost:1337', httpClient);

const App = () => (
    <Admin authProvider={authProvider} dataProvider={dataProvider}>
        <Resource name="posts" list={PostList} />
    </Admin>
);

export default App;

AuthProvider not working?

Strapi User-permission plugin expects you to send username and password in the following format

{
...
    identifier: 'your_username',
    password: 'password'
...
}

So in your front end form, the name for the username input should be identifier

However, an easier fix is to modify the Auth.js file To do that, in your project folder, go to plugins/user-permissions/controllers/Auth.js Then add the following line:

params.identifier = params.identifier ? params.identifier : params.username;

above this if statement

if (!params.identifier) {
    return ctx.badRequest(null, ctx.request.admin ? [{ messages: [{ id: 'Auth.form.error.email.provide' }] }] : 'Please provide your username or your e-mail.');
}

So it should look like this:

...
// The identifier is required.
params.identifier = params.identifier ? params.identifier : params.username;
if (!params.identifier) {
return ctx.badRequest(null, ctx.request.admin ? [{ messages: [{ id: 'Auth.form.error.email.provide' }] }] : 'Please provide your username or your e-mail.');
}
...

Example of a working authProvider.js

// authProvider.js

import { AUTH_LOGIN, AUTH_LOGOUT, AUTH_ERROR, AUTH_CHECK, AUTH_GET_PERMISSIONS } from 'react-admin';
import Cookies from './helpers/Cookies';

export default (type, params) => {
    if (type === AUTH_LOGIN) {
        const { username, password } = params;
        const request = new Request('http://localhost:1337/auth/local', {
            method: 'POST',
            body: JSON.stringify({ username, password }),
            headers: new Headers({ 'Content-Type': 'application/json'})
        });
        return fetch(request)
            .then(response => {
                if (response.status < 200 || response.status >= 300) {
                    throw new Error(response.statusText);
                }
                return response.json();
            })
            .then(response => {
                Cookies.setCookie('token', response.jwt, 1);
                Cookies.setCookie('role', response.user.role.name, 1);
            });
    }

    if (type === AUTH_LOGOUT) {
        Cookies.deleteCookie('token');
        Cookies.deleteCookie('role');
        return Promise.resolve();
    }

    if (type === AUTH_ERROR) {
        const status  = params.status;
        if (status === 401 || status === 403) {
            Cookies.deleteCookie('token');
            Cookies.deleteCookie('role');
            return Promise.reject();
        }
        return Promise.resolve();
    }

    if (type === AUTH_CHECK) {
        return Cookies.getCookie('token') ? Promise.resolve() : Promise.reject();
    }

    if (type === AUTH_GET_PERMISSIONS) {
        const role = Cookies.getCookie('role');
        return role ? Promise.resolve(role) : Promise.reject();
    }
    return Promise.resolve();
}

// ====================
// helpers/Cookies.js

const Cookies = {
	getCookie: (name) => {
		const v = document.cookie.match('(^|;) ?' + name + '=([^;]*)(;|$)');
    		return v ? v[2] : null;
	},

	setCookie: (name, value, days) => {
		var d = new Date();
    		d.setTime(d.getTime() + 24*60*60*1000*days);
    		document.cookie = name + "=" + value + ";path=/;expires=" + d.toGMTString();
	},

	deleteCookie: (name) => {
		Cookies.setCookie(name, '', -1)
	}
};

export default Cookies;

Using cookies instead of localStorage because localStorage does not play well with private browsing
