GraphQL client command line

Simple command line to query any GraphQL servers.

• Sample default configuration with GraphQLHub server endpoint
• Supports basic auth, fragments and mutations

Installation

$ npm install grql -g

Install a bundled version to $HOME/bin :

$ npm run installbin

Configuration

The configuration is stored into $HOME/.grql.yml, including environments settings and named queries.

Usage

Show help :

$ grql --help

Example of query : get a Giffy image from GraphQLHub

$ grql query '{ giphy { random(tag:"superbike") { url } } }'

Result :

{
  "giphy": {
    "random": {
      "url": "http://giphy.com/gifs/rhmit-xKi2gX2tY7h3q"
    }
  }
}

Use YAML output format :

$ grql query '{ giphy { random(tag:"superbike") { url } } }' -y

Result :

giphy: 
  random: 
    url: http://giphy.com/gifs/gtr-UUWYxAvgO60X6

Show configured environments :

$ grql -e
environnements :
[ ] graphqlhub
[o] myenv
[ ] anotherenv

Specify your own graphql server :

$ grql --baseurl https://mysupergraphql.server/graphql query "{ myquery(foo: "bar") }"

Save own graphql server to a named configuration :

$ grql --baseurl https://mysupergraphql.server/graphql \
  --conf mysuperserver --save \
  query '{ myquery(foo: "bar") }'

Save a query :

$ grql --alias myquery query '{ myquery(foo: "bar") }' --save

Next, to replay the query :

$ grql --alias myquery query

Query

The query content is passed either by command argument :

$ grql query '{ contact { username: "jdoe"} }'

or by stdin :

$ echo '{ contact { username: "jdoe"} }' | grql query 

Fragments

Save a new fragment :

$ cat << EOM | grql fragment gifInfo -s
fragment on GiphyGIFData {
  id
  url
  images {
    original {
      url
    }
  }
}
EOM

Use it in a query :

$ grql query '{ giphy { random(tag:"superbike") { ...${gifInfo} } } }' -y

Mutations

Change my details with my contacts graphql server :

$ cat << EOM | grql -e contacts mutate
{
  patchMe(input: {firstName: "John", lastName: "Doe"}) {
    id
    firstName
    lastName
    email
    username
  }
}
EOM

• env : show current environment or select the specified environment
• nocolor : disable color mode
• alias : select an alias to save or play
