Client SDKs

Currently, we offer the following Client SDKs:

• Node.js
• Go

For languages where an SDK isn't available yet, we encourage using the OpenAPI definition. We recommend using the OpenAPI Generator to generate your own client.

Development

For an optimal developer experience, it is recommended to install Nix and direnv.

Installing Nix and direnv

Note: These are instructions that SHOULD work in most cases. Consult the links above for the official instructions for your OS.

Install Nix:

sh <(curl -L https://nixos.org/nix/install) --daemon

Consult the installation instructions to install direnv using your package manager.

On MacOS:

brew install direnv

Install from binary builds:

curl -sfL https://direnv.net/install.sh | bash

The last step is to configure your shell to use direnv. For example for bash, add the following lines at the end of your ~/.bashrc:

eval "\$(direnv hook bash)"

Then restart the shell.

For other shells, see https://direnv.net/docs/hook.html.

MacOS specific instructions

Nix may stop working after a MacOS upgrade. If it does, follow these instructions.
