Package Exports

fake-json-api-server

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (fake-json-api-server) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Fake JSON-api server

Simple json-api server running in browser or node environment. Intercepts client XHR requests for defined routes when running in browser. Useful for test runners and setting up fake backend api server for client applications.

Visit documentation site.

Fake json api server processes data per json:api specification. It can be easily configured to handle (paginated) get, post, put and delete requests for user defined resources. Define dataset, filters and validation rules for each entity. Loaded dataset can be persisted to localStorage in browser.

Examples and api

Create fake server instance with configuration object.

new FakeJsonApiServer({
    baseApiUrl: '/api',
    resources: {
        tag: {
            data: [{
                type: 'tag',
                id: '1',
                attributes: {title: 'Tag 1'}},
            {
                type: 'tag',
                id: '2',
                attributes: {title: 'Tag 2'}
            }]
        }
    }
});

$.get('/api/tag', function(tagList) {
    // process tags json:api formatted data
});

$.get('/api/tag/1', function(tagData) {
    // process api data of tag with id 1
});

Persisting data to localStorage, setting up filters and validation rules for post and put request can be defined like so:

new FakeJsonApiServer({
    baseApiUrl: '/api',
    storageKey: 'fakeServerStorage',
    resources: {
        article: {
            filters: {
                title: function(title, query) {
                    return title.toLowerCase().indexOf(query.toLowerCase()) >= 0;
                }
            },
            validationRules: {
                title: {
                    rule: function(title) {
                        return title.length > 0;
                    },
                    message: 'Please enter title.'
                }
            },
            data: function(random) {

                return _.chain(_.range(1, 9)).map(function(index) {
                    return {
                        type: 'article',
                        id: String(index),
                        attributes: {
                            title: 'Article title ' + index,
                            leadTitle: 'Article lead title ' + index,
                            published: random.boolean()
                        },
                        relationships: {
                            author: {data: {id: random.id(1, 5), type: 'user'}},
                            tags: {
                                data: [
                                    {id: random.id(1, 5), type: 'tag'},
                                    {id: random.id(6, 10), type: 'tag'},
                                    {id: random.id(1, 10), type: 'tag'}
                                ]
                            }
                        }
                    };
                }).value();

            }
        }
    }
});

Node server setup

Following code will run fake json api server on localhost port 3000.

// server.js
var FakeServer = require 'fake-json-api-server/src/nodeServer';

new FakeServer({
    port: 3000,
    resources: {
        tag: {
            data: [{
                type: 'tag',
                id: '1',
                attributes: {title: 'Tag 1'}},
            {
                type: 'tag',
                id: '2',
                attributes: {title: 'Tag 2'}
            }]
        }
    }
});

node server.js

Api is now setuped to serve tag resources in json-api format on http://localhost:3000/tag

Installation

FakeJsonApiServer is packaged as UMD library so you can use it in CommonJS and AMD environment or with browser globals.

npm install fake-json-api-server --save

// with bundlers
var FakeJsonApiServer = require('fake-json-api-server');

// with browser globals
var FakeJsonApiServer = window.FakeJsonApiServer;
