FakeRest Data Provider For vn-kooch-react-admin

Client-side data provider for vn-kooch-react-admin, the frontend framework for building admin applications on top of REST/GraphQL services.

This package takes a JSON object as input, then creates a client-side data provider around it - no backend involved. The provider issues no HTTP requests, every operation happens locally in the browser. It's ideal to run e2e tests without an API server, or to showcase an admin only with a static server.

All operations carried out in vn-kooch-react-admin are local to the browser, and last only for the current browser session. A browser refresh erases all modifications.

Installation

npm install --save vn-kooch-data-fakerest

Usage

Pass a JSON object to the provider constructor:

// in src/App.js
import React from 'react';
import { Admin, Resource } from 'vn-kooch-react-admin';
import fakeDataProvider from 'vn-kooch-data-fakerest';

const dataProvider = fakeDataProvider({
    posts: [
        { id: 0, title: 'Hello, world!' },
        { id: 1, title: 'FooBar' },
    ],
    comments: [
        { id: 0, post_id: 0, author: 'John Doe', body: 'Sensational!' },
        { id: 1, post_id: 0, author: 'Jane Doe', body: 'I agree' },
    ],
})

import { PostList } from './posts';

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

export default App;

Additionally, you can turn on console logging of fake requests by passing true as second parameter of the constructor.

Input Format

The main parameter must be an object literal with one key for each resource type. Values are arrays of resources. Resources must be object literals with at least an id key.

Foreign keys are also supported: just name the field {related_resource_name}_id and give an existing value.

Here is an example input:

{
    "posts": [
        { "id": 0, "title": 'Hello, world!' },
        { "id": 1, "title": 'FooBar' }
    ],
    "comments": [
        { "id": 0, "post_id": 0, "author": 'John Doe', "body": 'Sensational!' },
        { "id": 1, "post_id": 0, "author": 'Jane Doe', "body": 'I agree' }
    ]
}

You can find a more sophisticated example in the Posters Galore demo.

Logging

Pass true as second argument to log the requests made to the provider in the console. This is very helpful to debug the requests made by an app using this data provider.

// in src/App.js
import React from 'react';
import { Admin, Resource } from 'vn-kooch-react-admin';
import fakeDataProvider from 'vn-kooch-data-fakerest';

const dataProvider = fakeDataProvider({ /* data here */ }, true);

const App = () => (
    <Admin dataProvider={dataProvider}>
        // ...
    </Admin>
);

Features

This data provider uses FakeRest under the hood. That means that it offers the same features:

• pagination
• sorting
• filtering by column
• filtering by the q full-text search
• filtering numbers and dates greater or less than a value
• embedding related resources
