Install pre-built rock

Simply run from the root of Tarantool Cartridge App root the following:

    cd <tarantool-cartridge-application-dir>
    tarantoolctl rocks install graphqlide

Lua API

Note: This module is still under heavy development. API may be changed in further versions without notice and may be not backward compatible. Use in production environments at your own risk.

Init

init() - used to initialize graphqlide module for non-Cartridge Tarantool Applications.

Stop

stop() - used to deinitialize graphqlide module for non-Cartridge Tarantool Applications.

Set endpoint

set_endpoint(endpoint) - used to set GraphQL Web UI schema endpoint in runtime.

where:

  • endpoint (table) - mandatory, endpoint of GraphQL API description with the following options:
    • name (string) - mandatory, schema display name;
    • path (string) - mandatory, URI-path to graphql endpoint;
    • default (boolean) - optional, flag to indicate that this endpoint is default, false - if not;
    • options (table) - optional, set of flags to enable or disable extended graphql schema fields, where:
      • descriptions (boolean) - optional, option to request or not for input fields descriptions, default is true;
      • specifiedByUrl - optional, option to request or not for specifiedByUrl field for Scalars, default is true;
      • directiveIsRepeatable - optional, option to request or not for directiveIsRepeatable field of Directives, default is true;
      • schemaDescription - optional, option to request or not for schemaDescription field for schema, default is false;
      • inputValueDeprecation - optional, option to deprecate or not for deprecated input fields, default is false;

Example:

    graphqlide.set_endpoint({ name = 'Spaces', path = '/admin/graphql', default = true })
    graphqlide.set_endpoint({
        name = 'Admin',
        path = '/admin/api',
        options = {
            specifiedByUrl = false,
            directiveIsRepeatable = false,
        }
    })

Note: Since Tarantool Cartridge WebUI doesn't support sending notifications to WebUI front after any changes feel free to reload page in browser

Get endpoints

get_endpoints() - method is used to get schemas endpoints.

Method returns endpoints (table) with the following structure:

    {
        ["<endpoint_name>"] = { 
            default = true/false,
            path = "<endpoint_path>", 
            options = {
                descriptions = true/false,
                specifiedByUrl = true/false,
                directiveIsRepeatable = true/false,
                schemaDescription = true/false,
                inputValueDeprecation = true/false,
            } 
        },
        ...
    }

Remove endpoints

remove_endpoint(name) - method is used to remove schema endpoint,

where:

  • name (string) - mandatory, schema display name.

Example:

    graphqlide.set_endpoint({ name = 'Spaces', path = '/admin/graphql', default = true })

    ...

    graphqlide.remove_endpoint('Spaces')

Front init

front_init(httpd, opts) - method to init frontend core. This method must be used only for non-Cartridge Tarantool Applications since Tarantool Cartridge do this job for you under the hood,

where:

  • httpd (table) - instance of a Tarantool HTTP server (only 1.x versions is supported).
  • opts (table) - optional, additional front-end initialization options:
    • enforce_root_redirect (boolean) - optional key which controls redirection to frontend core app from '/' path, default true;
    • prefix (string) - optional, adds path prefix to frontend core app;
    • force_init (boolean) - optional, flag to force frontend module initialization. By default front_init() checks whether frontend core module initialized or not, but if force_init == true front_init() will skip checks and init frontend core module anyways.

Set default schema

set_default(name) - method to set default schema,

where:

  • name (string) - mandatory, schema display name to be set as default.

Add Tarantool Cartridge GraphQL API schema endpoint

add_cartridge_api_endpoint(name, default) - method to add Tarantool Cartridge GraphQL API schema endpoint,

where:

  • name (string) - mandatory, Tarantool Cartridge GraphQL API schema name to be displayed in UI;
  • default (boolean) - optional, flag to set this schema to be default in list of GraphQL schemas in UI.

Note: This method will not be available if executed in non-Cartridge Tarantool Application.

Remove Tarantool Cartridge GraphQL API schema endpoint

remove_cartridge_api_endpoint() - method to remove Tarantool Cartridge GraphQL API schema endpoint from list of schemas in GraphQL IDE UI.

Note: This method will not be available if executed in non-Cartridge Tarantool Application.

Version

VERSION - is a constant to determine which version of GraphQL IDE is installed.

Example:

    local graphqlide = require('graphqlide')
    local log = require('log')
    log.info('GraphQL IDE version: %s', graphqlide.VERSION)

Adding GraphQL IDE to your Tarantool Cartridge App

There are 3 ways to add GraphQL IDE to Tarantool Cartridge application:

  1. Add GraphQL IDE initialization code to Tarantool Cartridge application init.lua:
    ...

    local ok, err = cartridge.cfg({
        roles = {
            ...
        },
    })

    assert(ok, tostring(err))

    -- Init GraphQL IDE
    local endpoint = '/admin/graphql'
    require('graphqlide').init()
    graphqlide.set_endpoint({ name = 'Spaces', path = '/admin/graphql', default = true })
    ...

Note: graphqlide.init() must be called after cartridge.cfg()

  1. Add GraphQL IDE initialization code into desired Tarantool Cartridge role init() function:
    local graphqlide = require('graphqlide')
    ...

    local function init(opts) -- luacheck: no unused args
        if opts.is_master then
            ...
        end
        ...

        -- Init GraphQL IDE
        graphqlide.init()
        -- Set GraphQL endpoint
        graphqlide.set_endpoint({ name = 'Spaces', path = '/admin/graphql', default = true })
        return true
    end

    local function stop()
        -- Deinit GraphQL IDE
        graphqlide.stop()
        ...
    end

    ...

    return {
        role_name = 'app.roles.custom',
        init = init,
        stop = stop,
        dependencies = {
            'cartridge.roles.graphqlide',
        }
    }
  1. Add GraphQL IDE Tarantool Cartridge role as dependency of desired Tarantool Cartridge role:
    ...
    local function init(opts) -- luacheck: no unused args
        if opts.is_master then
            ...
        end
        ...

        -- Init GraphQL IDE
        graphqlide.init()
        graphqlide.set_endpoint({ name = 'Spaces', path = '/admin/graphql', default = true })
        return true
    end

    local function stop()
        -- Deinit GraphQL IDE
        graphqlide.stop()
        ...
    end
    ...
    return {
        role_name = 'app.roles.custom',
        init = init,
        stop = stop,
        dependencies = {
            'cartridge.roles.graphqlide',
        }
    }

In this case may need to set endpoint of GraphQL API. The best way to it simply call set_endpoint() method from init() of Tarantool Cartridge role:

    local graphqlide = require('graphqlide')
    ...
    local function init(opts)
        if opts.is_master then
        ...
        end
        ...
        graphqlide.set_endpoint('/admin/graphql')
        ...
    end

Use GraphQL IDE with pure Tarantool (without Tarantool Cartridge)

This module can be used with pure Tarantool (without Tarantool Cartridge).

Caution: GraphQL IDE module is compatible only with 1.x branch of http module http

Example:

    local http = require('http.server')
    local graphqlide = require('graphqlide')

    local HOST = '0.0.0.0'
    local PORT = 8081
    local ENDPOINT = '/graphqlide'

    local httpd = http.new(HOST, PORT,{ log_requests = false })

    httpd:start()
    -- Init frontend-core module if it was not initialized before
    graphqlide.front_init(httpd)

    -- Init graphqlide module if it was not initialized before
    graphqlide.init()

    -- set default "Default" GraphQL endpoint 
    graphqlide.set_endpoint({ name = 'Default', path = ENDPOINT, default = true })

    box.cfg({work_dir = './tmp'})
