# ForceJS - JavaScript Toolkit for Salesforce APIs
ForceJS is a micro-library that makes it easy to use the Salesforce REST APIs in JavaScript applications. ForceJS allows you to easily authenticate with Salesforce using OAuth, and to manipulate Salesforce data using a simple API.
The main target of ForceJS are:
- Client-side JavaScript applications deployed on your own server (Heroku or elsewhere)
- Hybrid mobile apps built with Apache Cordova and the Salesforce Mobile SDK
Applications deployed inside a Salesforce instance (Visualforce Page or Lightning Components) can use one of the data access utilities built into the Salesforce Platform instead: JavaScript Remoting, Remote Objects, Lightning Data Service, etc.
## Built on ECMAScript 6
Modern JavaScript applications now use ECMAScript 6 (aka ECMAScript 2015) and beyond. The current version of modern frameworks (such as React, Angular 2, and Ionic 2) are also built on top of ECMAScript 6 and beyond.
To support modern application development, and to integrate nicely with these frameworks, ForceJS is now built on top of ECMAScript 6 as well.
## Compatible with ECMAScript 5
The ECMAScript 6 source files are compiled into an ECMAScript 5 compatible version. The ECMAScript 5 compatible files are available in the `dist` directory. The ECMAScript 5 files support the Universal Module Definition (UMD) format. In other words, they can be used with AMD or CommonJS module loaders as well as globally using the `force.OAuth` and `force.DataService` variables.
> The original ECMAScript 5-only version of forcejs is still available in the [es5 branch](https://github.com/ccoenraets/forcejs/tree/es5) of this repository. The es5 branch is no longer actively developed.
## Key Characteristics
- No dependency
- Loaded as an ECMAScript 6 module
- Asynchronous calls return ECMAScript 6 promises
- Complete OAuth login workflow (User Agent)
- Works transparently in the browser and in Cordova using the Salesforce Mobile SDK OAuth plugin
- Automatically refreshes OAuth access_token (if available) on expiration
- Tightly integrated with [force-server](https://github.com/ccoenraets/force-server), a local development server that works as a proxy and a local web server to provide a streamlined developer experience
- Simple API to manipulate data (create, update, delete, upsert)
- Supports connections to multiple instances of Salesforce in the same application
- Works with modern JavaScript frameworks: React, Angular 2, Ionic 2, etc.
## Modular
ForceJS is built on a modular architecture. It currently includes two modules:
- **forcejs/oauth**: A module that makes it easy to authenticate with Salesforce using the OAuth User Agent workflow
- **forcejs/data-service**: A module that makes it easy to access data through the Salesforce APIs
`forcejs/oauth` and `forcejs/data-service` are typically used together in an application, but you can use them separately. For example, you could use **forcejs/oauth** by itself if all you need is a Salesforce access token (Lightning Out use cases). Similarly, you could use **forcejs/data-service** by itself if you already have an access token, and all you need is a simple library to access the Salesforce APIs.
## Browser and Cordova Abstraction
ForceJS can be used to develop browser-based apps or hybrid mobile apps using the Salesforce Mobile SDK and Apache Cordova. If you develop a hybrid application using the Salesforce Mobile SDK, you often switch back and forth between running the app in the browser and on device. Developing in the browser is generally faster and easier to debug, but you still need to test device-specific features and check that everything runs as expected on the target platforms. The problem is that the configuration of OAuth and REST is different when running in the browser and on device. Here is a summary of the key differences:
BrowserMobile SDK
Requires ProxyYes(*)No
OAuthWindow PopupOAuth Plugin
(*) Starting in the Spring 15 release, some Salesforce REST APIs (like Chatter and sobjects) support CORS. To allow an app to make direct REST calls against your org, register the app domain in Setup: Administer > Security Controls > CORS.
ForceJS abstracts these differences and allows you to run your app in the browser and on device without code or configuration changes.
## ECMAScript 6 Usage
```javascript
import {OAuth, DataService} from 'forcejs';
let oauth = OAuth.createInstance();
oauth.login().then(oauthResult => DataService.createInstance(oauthResult));
let loadContacts = () => {
let service = DataService.getInstance();
service.query('select id, Name from contact LIMIT 50')
.then(response => {
let contacts = response.records;
// do something with contacts
});
}
```
If you are only using one of the forcejs submodules (either oauth or data), the following import syntax is recommended to make sure the compiled version does not include the module you don't use if your build tool doesn't support tree shaking:
``` javascript
import OAuth from 'forcejs/oauth';
//or
import DataService from 'forcejs/data-service';
```
Because current browsers don't yet support all the ECMAScript 6 features, you need to use a build tool to compile (transpile) your ECMAScript 6 code to ECMAScript 5 compatible code, and provide the module loading infrastructure.
Webpack, Browserify, and Rollup are popular options. Webpack instructions are provided in the Quick Start sections below. Frameworks like React, Angular 2, and Ionic 2 already come with a build process. If you are using these frameworks, no additional step is necessary.
## ECMAScript 5 Usage
Use the ECMAScript 5 compatible files available in the `dist` directory.
```html
var oauth = force.OAuth.createInstance();
oauth.login().then(function(oauthResult) {
force.DataService.createInstance(oauthResult);
});
function loadContacts() {
var service = force.DataService.getInstance();
service.query('select id, Name from contact LIMIT 50')
.then(function(response) {
var contacts = response.records;
// do something with contacts
});
}
```
If you are only using one of the forcejs modules (either oauth or data), the following syntax is recommended to avoid including modules you don't use:
```html
// or
var oauth = force.OAuth.createInstance();
// or
var service = force.DataService.createInstance(oauthResult);
```

## API Reference
### forcejs/oauth
Basic Usage:
import OAuth from "forcejs/oauth";
let oauth = OAuth.createInstance();
oauth.login().then(result => {
console.log(result); // Prints access token, instance URL, and refresh token (if any)
});
#### createInstance(appId, loginURL, oauthCallbackURL)
- **appId**
The Salesforce Connected App Id. For convenience, ForceJS uses a default connected app if the appId is not provided. The default connected app supports http://localhost:8200/oauthcallback.html as the OAuth callback URL to provide an out-of-the-box development experience using force-server. You need to create your own connected app with your own OAuth callback URL to run your application on a different server and port.
*Optional*
*Default:* 3MVG9fMtCkV6eLheIEZplMqWfnGlf3Y.BcWdOf1qytXo9zxgbsrUbS.ExHTgUPJeb3jZeT8NYhc.hMyznKU92
- **loginURL**
The URL for the login window that should be used as part of the OAuth process.
*Optional*
*Default*: https://login.salesforce.com
- **oauthCallbackURL**
The URL Salesforce calls back with an authenticated access token (or an error) at the end of the OAuth authentication workflow.
*Optional*
*Default*: The base URL the application was loaded from. For example, if you load the app from http://localhost:8200, the default OAuth callback URL is http://localhost:8200/oauthcallback.html. If you load the app from https://myserver.com/myapp, the default OAuth callback URL is https://myserver.com/myapp/oauthcallback.html
#### login()
Starts the User Agent OAuth workflow using a popup window when running in the browser or the oauth plugin when running in Cordova.
- **Return Value**: A promise. When resolved, an object with the following fields is provided: **appId**, **accessToken**, **instanceURL**, **refreshToken**, and **userId**.
## forcejs/data-service
Basic Usage:
import Oauth from "forcejs/oauth";
import Service from "forcejs/data-service";
let oauth = OAuth.createInstance();
oauth.login().then(oauthResult => {
Service.createInstance(oauthResult);
});
#### createInstance(oauth, options, name)
- **oauth**. Required. An object with the following fields:
- **accessToken**
The authenticated access token
Required, no default
- **instanceURL**
The Salesforce instance URL
Required, no default
- **refreshToken**
The refresh token
Optional, no default
- **options**. Optional. An object with the following fields:
- **useProxy**.
By default, ForceJS will automatically determine if it needs to use a CORS proxy: It won't use a proxy if the app is running inside a Visualforce page or a Cordova app, and will use the proxy in any other case. You can force ForceJS to always use a proxy by setting this value to true.
Starting in the Spring 15 release, some Salesforce REST APIs (like Chatter and sobjects) support CORS. To allow an app to make direct REST calls against your org, register the app domain in Setup: Administer > Security Controls > CORS. If you whitelist your domain and use APIs that support CORS, you can set useProxy to false.
Optional. Default: **false** if the app is running in Cordova or in a Visualforce page, **true** if it's not.
- **proxyURL**.
The URL of the CORS proxy server. This parameter is ignored when the app is running in Cordova or inside a Visualforce page.
Optional. Default: The base URL the application was loaded from. For example, if you load the app from http://localhost:8200, the default proxyURL is http://localhost:8200. If you load the app from https://myserver.com/myapp, the default proxyURL is https://myserver.com/myapp
- **apiVersion**
The version of the Salesforce API.
Optional. Default: v36.0
- **name**
By default createInstance() creates a singleton instance which is what you want when your app works with a single Salesforce org. If you are building an app that connects to multiple Salesforce instances, provide a name that identifies the instance. For example:
```
createInstance(oauth, options, "sales");
```
You can later retrieve that specific instance using:
```
getInstance("sales");
```
Optional. Default: none. If a name is not provided a singleton instance is created. If a name is provided, a named instance is provided.
#### getInstance(name)
- **name**
The name of the instance you want to retrieve.

- **batch** (optional): save query for batch call - see more under **.batch()**
#### describe(objectName)
Completely describes the individual metadata at all levels for the specified object.
- **objectName**: object name; e.g. "Account"

#### batch(requests)
Executes batch commands
the batch parameter in the other calls like query, create will save the request for the batch.
So you have to call before you execute this function.
Important note:
In API version 34.0 and later, subrequests can be calls to the Limits, SObject, Query/QueryAll, Search, Connect,
and Chatter resources. API version 35.0 adds the ability to use Actions resources.
