Hasura GraphQL Engine CLI

Installation

Download GraphQL Engine CLI bundled with Hasura CLI

• Linux/macOS

  curl -L https://github.com/hasura/graphql-engine/raw/stable/cli/get.sh | bash
  

  This will install the Hasura CLI in /usr/local/bin. You might have to provide your sudo password depending on the permissions of your /usr/local/bin location.

  If you’d prefer to install to a different location other than /usr/local/bin, set the INSTALL_PATH variable accordingly:

  curl -L https://github.com/hasura/graphql-engine/raw/stable/cli/get.sh | INSTALL_PATH=$HOME/bin bash
  

  You can also install a specific version of the CLI by providing the VERSION variable:

  curl -L https://github.com/hasura/graphql-engine/raw/stable/cli/get.sh | VERSION=v2.2.0 bash
  

• Windows

  Download the binary cli-hasura-windows-amd64.exe available under Assets of the latest release from the GitHub release page: https://github.com/hasura/graphql-engine/releases

Download using go get

go get github.com/hasura/graphql-engine/cli/cmd/hasura

Build from source

git clone https://github.com/hasura/graphql-engine
cd graphql-engine/cli
make deps
make build-cli-ext copy-cli-ext
make build
# binaries will be in _output directory

Usage

hasura init --directory <my-project> --endpoint <graphql-endpoint> --admin-secret <admin-secret>
cd <my-project>
hasura console

Overview

Package cli and it's sub packages implements the command line tool for Hasura GraphQL Engine. The CLI operates on a directory, denoted by "ExecutionDirectory" in the "ExecutionContext" struct.

The ExecutionContext is passed to all the subcommands so that a singleton context is available for the execution. Logger and Spinner comes from the same context.
