The Node.js SDK seamlessly integrates with The Things Network's LoRaWAN Network Server (LNS), allowing developers to easily connect and manage IoT devices. With extensive API support, this package simplifies application interaction with TTN's LoRaWAN ecosystem, enabling device provisioning, data transmission, and device status monitoring. Utilize the user-friendly Node.js SDK to boost connectivity and data management within The Things Network's LoRaWAN infrastructure.
This SDK also works with "The Things Industries" and privately hosted "The Things Stack Instance".

To install the latest version on npm locally and save it in your package's package.json file:
npm install the-things-network --save
To install a particular version:
npm install the-things-network@version --save
Let's say you want to create an application, it can be created for both User and Organization...
- First import that particular class.
- Then set user ID and the configuration.
- Pass the payload in the method.
For more info, see this: Create Application For User
import { User } from 'the-things-network';
//just an example of config
const config = {
IDENTITY_SERVER: 'eu1.cloud.thethings.network',
NETWORK_SERVER: 'nam1.cloud.thethings.network',
APPLICATION_SERVER: 'nam1.cloud.thethings.network',
JOIN_SERVER: 'nam1.cloud.thethings.network',
API_KEY: 'xxxxxapi_keyxxxxxx',
};
//just an example of payload
const payload = {
application_id: 'test',
name: 'demo',
description: 'for testing',
};
const user = User('userId', config);
const result = async () => {
try {
const resp = await user.createApplication(payload);
console.log(resp);
} catch (err) {
console.log(err);
}
}
result();
- First import that particular class.
- Then set organization ID and the configuration.
- Pass the payload in the method.
For more info, see this: Create Application For Organization
import { Organization } from 'the-things-network';
//just an example of config
const config = {
IDENTITY_SERVER: 'eu1.cloud.thethings.network',
