mtcute/packages/client/src/methods

What is this?

Files in this directory are pre-processed by generate-client.js, and client.ts is generated from the functions that are exported in this directory.

Since we need to properly type the copied signatures, there are a few "magic" instructions for the preprocessor that are used to handle imports. Also, there are a few "magic" instructions to make private methods and extend client fields.

All instructions are used as a one-line comment, like this: // @copy

@copy

Can be placed before an import or any other code block.

When placed before import, this import will be copied to client.ts, and paths will be adjusted. When there are multiple copied imports from the same files, they are merged.

When placed before any other block, it will be directly copied before the TelegramClient class.

Note

all copied imports should be inside _imports.ts file.

Example:

// @copy
import { Something } from '../../somewhere.js'

// @copy
interface SomeGreatInterface { ... }

@extension

Used before an interface declaration. Fields from that interface will be added as protected to TelegramClient.

Example:

// @extension
interface AwesomeExtension {
    _field1: number
    _field2: string
}

@initialize

Often you'll want to initialize your @extension fields in a constructor. You can do this by using @initialize instruction before a function containing initialization code.

Note

If you are using some custom types, make sure their imports are copied!

Example:

// @initialize
function _initializeAwesomeExtension(client: BaseTelegramClient) {
    this._field1 = 42
    this._field2 = 'uwu'
}

@exported

Used as a first statement inside an exported function's body to indicate that this exported type should be imported from the client

Example:

// @exported
export type FooOrBar = Foo | Bar

export function getFooOrBar(client: BaseTelegramClient): FooOrBar {
    return new Foo()
}
