How to use the methods of client

Next, How to use the methods of client?

It's easy.

All you have to do is call the client's method as follows.

import { Client } from "@evex/linejs";

const client = new Client();

client.on("pincall", (pincode) => {
	console.log(`pincode: ${pincode}`);
});

client.on("ready", async (user) => {
	console.log(`Logged in as ${user.displayName} (${user.mid});`);

	console.log(await client.getProfile());
});

await client.login({
	email: "YOUR_EMAIL",
	password: "YOUR_PASSWORD",
});

// or, you can log in using the QR code.
await client.login({
	qr: true,
});

The output will be as follows.

console

{
	mid: "u**********",
	phone: "***********",
	regionCode: "JP",
    ...
}

I will tell you one thing here.
When you log in, you can use a better choice.

Logging in repeatedly with email may be regarded as fraudulent login
and your account may be temporarily restricted (though only for a few days), and above all, It is very cumbersome.

It is therefore a good idea to use an AuthToken.

A temporary token is used for email login.
Therefore, after a few days, it will expire and the client will stop running.
So, if you want to run the client permanently, you must use v1.

It would be a good idea to use v2 during development.
Repeating the email login multiple times is highly discouraged.

Now, let's look at how to get token.

Simply write the following.
It's easy.

client.on("update:authtoken", (authtoken) => {
	console.log("AuthToken", authtoken);
});

The output will be as follows.

console

AuthToken **********.********

This is the v2 token. It can be used as follows

await client.login({
	authToken: "YOUR_AUTH_TOKEN",
});

Important notice

However, this login method has pitfalls. LINE uses e2ee for encryption, but the key to decrypt it can only be obtained with an email login with pincode, or QR login.

Therefore, if you login only with an authToken, you will not be able to retrieve group talk events.
(Square (OpenChat) is possible.)

So how can we do this?　　 It's easy, too.

We just need to make the internal storage permanent and log in with email first only once.

LINEJS has internal storage for storing and caching.
By default, it is MemoryStorage, and it all disappears after one execution.

This can be FileStorage. As follows.

import { FileStorage } from "@evex/linejs/storage";

const client = new Client({
	storage: new FileStorage("./storage.json"), // path to storage file (This is secret file)
});

You only need to log in once first with your email and then use your authToken.

This concludes our first trip.
But there is still a journey left to be made.
Enjoy.

TIP

If you want to create your own storage such as connecting to the cloud api,
import BaseStorage and extend it to create your own storage. (Please ask for details.)

INFO

If you want to use v1, please ask for details at discord.gg/evex.
