evrythng.js is the official JavaScript SDK for developers writing web apps in the browser or server-side with platforms such as Node.js. It presents a fluent Promise-driven API that allows programmatic access to all resources available through the standard REST API.
Installation
A summary of the various installation methods is shown here, but for detailed installation instructions, see the Installation section of the repository README.
CDN
Install with a script tag:
<script src="https://d10ka0m22z5ju5.cloudfront.net/js/evrythng/6.0.0/evrythng-6.0.0.js"></script>
Include: Available globally as evrythng
npm
Install: npm install --save evrythng
Include: Require as a dependency in the usual manner within the application JavaScript code:
const evrythng = require('evrythng');
// Or using ES6 modules
import * as evrythng from 'evrythng'
Setup Options
Once installed, evrythng.js can be optionally configured using setup(), with the following options:
-
apiUrl- String
Change the default API host, such ashttps://api.us.evrythng.io/v2. If not specified, this is determined using values given forapiVersionandregion. -
fullResponse- Boolean
Set totrueto access thestatusorheadersin responses. Can also be set on a per-request basis. -
quiet- Boolean
Set totrueto prevent anything being output to the console. -
geolocation- Boolean
Set totrueto ask for Geolocation when needed. When set totrue, following resources will use the resolved coordinates:.action().create(),.thng().location().update(),.place().read(). -
timeout- Integer
Set the default request timeout, in milliseconds -
apiKey- String
Set the authorization API key used for all raw requests -
interceptors- Object array
Register callbacks to be called on each request or response. An example is shown in theevrythng.jsrepository. -
defaultShortDomain- String
Set the default short domain to be used when dealing with redirections. -
apiVersion- Number
Set which API version to use:1or2. By default, apiVersion is2. Refer to the v2, or v1 (legacy) guides. -
region- String
Set region URL for defined API version. There are two supported regions:us, which is set by default, andeu.
For example, to set a global timeout and disable geolocation:
evrythng.setup({
timeout: 5000,
geolocation: false,
});
Scopes
The evrythng.js SDK includes scope objects that represent each type of API key and allows the developer to make requests with that key.
The following scopes for apiVersion:2 are available:
Operator- Operator API KeyAccessToken- Access Token API Key
Operator and AccessToken scopes can have a different set of permissions, which is defined on access policy and assigned during creation of operator access and access token.
The following scopes for apiVersion:1 are available:
Operator- Operator API KeyApplication- Application API KeyTrustedApplication- Trusted Application API KeyActionApp- Application API KeyUser- Application User API KeyDevice- Device API Key
Most scopes are initialized in the same way by supplying the API key to use (except Device, which also requires the ID and API key):
const evrythng = require('evrythng');
const app = new evrythng.Application(APPLICATION_API_KEY);
// Or using destructuring
import { Application } from 'evrythng';
const app = new Application(APPLICATION_API_KEY);
If the scope's metadata is required immediately, use init() to ensure this data has been fetched from the API and made ready for use:
const app = new evrythng.Application(APPLICATION_API_KEY);
// Wait for scope to read its data before using its customFields
app.init()
.then(() => console.log(app.customFields));
Making requests
All requests are made via a scope object, and return promises. This provides an easy to read and intuitive interface to write a chain of functions to form the request as a whole. In general, the format flows from the scope, to the resource type (such as thng or collection), to the resource method.
Methods include create, read, update, delete, rescope, upsert, find, stream, and streamPages.
In general, resource IDs are specified in that resource's method parameter list, and payloads are specified in the request method's parameter list. For example, to update a single Thng:
const thngId = 'Um52tPXf6mshhMRRagVN2sHf';
const payload = { tags: ['updated'] };
// Using Promises
user.thng(thngId).update(payload)
.then(console.log);
// Or async/await
const res = await user.thng(thngId).update(payload);
console.log(res);
Or to read a single page of products:
// Using Promises
operator.product().read()
.then(console.log);
// Or async/await
const products = await operator.product().read();
console.log(products);
See the Function Reference section for a more complete list of available functions.
Parameters
Request query parameters mirror those in the conventional REST API, and are specified in the request method as a parameter using either the params property, or chainable setters. For example, applying a filter:
// Using a params object
const params = {
filter: 'name=Test*',
perPage: 100,
};
operator.thng()
.read({ params })
.then(console.log);
// Or using chainable setters
operator.thng()
.setFilter('name=Test*')
.setPerPage(100)
.read()
.then(console.log);
Other examples of parameters specified in this way include: project, ids, perPage, withScopes, and context. Some of these are shown below for common scenarios:
// Specify filter as an object
const params = {
filter: {
name: 'Pallet*',
tags: 'shipped',
},
};
user.thng().read({ params })
.then(console.log);
// Specify filters as a string
const params = { filter: 'name=Pallet*&tags=shipped' };
user.thng().read({ params })
.then(console.log);
// Specify parameters such as project scope on creating a Thng
const projectId = 'UF6HgyNFVDswQKRRwhPK3kCg';
const payload = { name: 'Example Thng' };
const params = { project: projectId };
user.thng().create(payload, { params })
.then(console.log);
// Receive raw HTTP fetch response instead of model entity
user.product().read({ fullResponse: true })
.then(console.log);
// Read a single Thng with a certain tags pattern with context and scopes
const params = {
perPage: 1,
filter: 'tags=batch-*',
withScopes: true,
context: true,
};
user.action().read({ params })
.then(console.log);
The same examples using chainable setters:
// Specify filter as an object
user.thng()
.setFilter('name=Pallet*&tags=shipped')
.read()
.then(console.log);
// Specify parameters such as project scope on creating a Thng
const projectId = 'UF6HgyNFVDswQKRRwhPK3kCg';
const payload = { name: 'Example Thng' };
user.thng()
.setProject(projectId)
.create(payload)
.then(console.log);
// Read a single Thng with a certain tags pattern with context and scopes
user.action()
.setPerPage(1)
.setFilter('tags=batch-*')
.setWithScopes()
.setContext()
.read()
.then(console.log);
