GramJS
A Telegram client written in JavaScript for Node.js and browsers, with its core being based on
Telethon.
How to get started
Here you'll learn how to obtain necessary information to create telegram application, authorize into your account and send yourself a message.Note that if you want to use a GramJS inside of a browser, refer to this instructions.Install GramJS: ```bash $ npm i telegram ``` After installation, you'll need to obtain an API ID and hash:
- Login into your telegram account
- Then click "API development tools" and fill your application details (only app title and short name required)
- Finally, click "Create application"
Never share any API/authorization details, that will compromise your application and account.When you've successfully created the application, change
apiId and apiHash on what you got from telegram.
Then run this code to send a message to yourself.
```javascript
import { TelegramClient } from "telegram";
import { StringSession } from "telegram/sessions";
import readline from "readline";
const apiId = 123456;
const apiHash = "123456abcdfg";
const stringSession = new StringSession(""); // fill this later with the value from session.save()
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout,
});
(async () => {
console.log("Loading interactive example...");
const client = new TelegramClient(stringSession, apiId, apiHash, {
connectionRetries: 5,phoneNumber: async () =>new Promise((resolve) =>rl.question("Please enter your number: ", resolve)),password: async () =>new Promise((resolve) =>rl.question("Please enter your password: ", resolve)),phoneCode: async () =>new Promise((resolve) =>rl.question("Please enter the code you received: ", resolve)),onError: (err) => console.log(err),Note that you can also save auth key to a folder instead of a string, change stringSession into this:
```javascript
const storeSession = new StoreSession("foldername");
```Be sure to save output of
client.session.save() into stringSession or storeSession variable to avoid logging in again.
Running GramJS inside browsers
GramJS works great in combination with frontend libraries such as React, Vue and others. While working within browsers, GramJS is usinglocalStorage to cache the layers.
To get a browser bundle of GramJS, use the following command:
```bash
NODEENV=production npx webpack
```
You can also use the helpful script generate_webpack.js
```bash
node generatewebpack.js
```
