go-lichess

go-lichess is a Go client library for accessing the Lichess.org API (2.0.0).

Installation

go-lichess is compatible with modern Go releases in module mode, with Go installed:

go get github.com/joanlopez/go-lichess

will resolve and add the package to the current development module, along with its dependencies.

Alternatively the same can be achieved if you use import in a package:

import "github.com/joanlopez/go-lichess/lichess"

and run go get without parameters.

Finally, to use the top-of-trunk version of this repo, use the following command:

go get github.com/joanlopez/go-lichess@main

Usage

import "github.com/joanlopez/go-lichess/lichess" // with go modules enabled (GO111MODULE=on or outside GOPATH)

Construct a new Lichess client, then use the various services on the client to access different parts of the Lichess API. For example:

client := lichess.NewClient(nil)

// export games played by user "chucknorris"
games, _, err := client.Games.ExportByUsername(context.Background(), "chucknorris", nil)

Some API methods have optional parameters that can be passed. For example:

client := lichess.NewClient(nil)

// export (up to 5) games played by user "chucknorris"
max := 5
games, _, err := client.Games.ExportByUsername(context.Background(), "chucknorris", &lichess.ExportByUsernameOptions{Max: &max})

NOTE: Using the context package, one can easily pass cancellation signals and deadlines to various services of the client for handling a request. In case there is no context available, then context.Background() can be used as a starting point.

Authentication

Use the WithAuthToken method to configure your client to authenticate using an OAuth token (for example, a Personal Access Token).

client := lichess.NewClient(nil).WithAuthToken("... your access token ...")

Note that when using an authenticated Client, all calls made by the client will include the specified OAuth token. Therefore, authenticated clients should almost never be shared between different users.
