A complete Go library for the Telegram Bot API with one-to-one type and method mapping.
Telego is a Go library that provides a complete implementation of the Telegram Bot API, allowing developers to build and interact with Telegram bots. It mirrors the official API's types and methods one-to-one, solving the problem of manual API integration by offering a type-safe, feature-rich toolkit.
Go developers building Telegram bots who need a reliable, full-featured library with support for modern bot features like webhooks, handlers, and utility helpers.
Developers choose Telego for its exact API mapping, performance optimizations with fasthttp and go-json, and ergonomic utilities like telegoutil and predicate-based handlers, which streamline bot development compared to lower-level alternatives.
Telegram Bot API library for Go
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides a one-to-one mapping of Telegram Bot API types and methods with mirrored documentation, ensuring type safety and full coverage as evidenced by the generated types.go and methods.go files.
Defaults to fasthttp and go-json for HTTP requests and JSON handling, offering speed improvements over standard libraries, with benchmarks implied by the focus on efficiency.
Includes the telegoutil package with helper methods like Message() and ID() for convenient parameter creation, reducing boilerplate code in method calls.
Features a predicate-based handler system with middleware and groups, similar to net/http, enabling organized and scalable bot logic as shown in multiple examples.
The README admits that auto-generated types and methods may have errors or missing parts from Telegram's documentation, requiring manual verification for critical applications.
Relies on fasthttp and go-json by default, which can introduce compatibility issues or learning curves for teams standardized on net/http or encoding/json, despite build tag options.
Setting up webhooks requires additional configuration like TLS certificates and server integration, which is nontrivial for beginners, as noted in the Ngrok and Let's Encrypt tips.
