Algolia GraphQL Schema

Given an Algolia index, generates valid GraphQL types for exposing a GraphQL backend search Query

Configuration

algolia_graphql_config.json

{
  "algoliaIndex": "products",
  "algoliaAppId": "",
  "algoliaAdminApiKey": "",
  "algoliaSearchApiKey": "",
  "outputDir": "typedefs/",
  "outputFileName": "algolia",
  "searchQueryName": "search",
  "fallbackTypes": {
    "collections[]": "string"
  }
}

Example

For an Algolia index with the following objects:

[
  {
    "id": "e2866573-7591-4742-b2bc-891b78d679bd",
    "title": "Handcrafted Concrete Pants",
    "collections": ["Cotton"],
    "shipping": "Free shipping",
    "salePrice": 781
  },
  {
    "id": "a07d4dd8-7fc8-40b6-9879-cf6e0dd9efb7",
    "title": "Refined Soft Chicken",
    "collections": ["Fresh"],
    "salePrice": 657
  }
]

the following GraphQL types are generated:

type AlgoliaResultObject {
  id: String!
  title: String!
  collections: [String!]!
  salePrice: Int!
  shipping: String
}

type SearchResultsEdge {
  cursor: Int!
  node: AlgoliaResultObject
}

type SearchResults {
  edges: [SearchResultsEdge!]!
  totalCount: Int!
}

input SearchInput {
  query: String

  similarQuery: String

  # ...
}

type Query {
  # ...
  search_flights($input: SearchInput!, $after: String): [SearchResults!]!
}

Algolia search params support

Disclaimer

GraphQL does not support union on scalar types.

For this reason, the following Algolia search params have the following breaking GraphQL type definition changes:

• facetFilters?: string | readonly string[] | ReadonlyArray<readonly string[]>; ➡️ facetFilters: [String]
• optionalFilters?: string | readonly string[] | ReadonlyArray<readonly string[] | string>; ➡️ optionalFilters: [String]
• numericFilters?: string | readonly string[] | ReadonlyArray<readonly string[]>; ➡️ numericFilters: [String]
• tagFilters?: string | readonly string[] | ReadonlyArray<readonly string[]>; ➡️ tagFilters: [String]
• aroundRadius?: number | 'all'; ➡️ aroundRadius: Int
• aroundPrecision?: number | ReadonlyArray<{ from: number; value: number; }>; ➡️ aroundPrecision: Int
• ignorePlurals?: boolean | readonly string[]; ➡️ ignorePlurals: Boolean
• removeStopWords?: boolean | readonly string[]; ➡️ removeStopWords: Boolean
• distinct?: boolean | number; ➡️ distinct: Boolean
• optionalWords?: string | readonly string[]; ➡️ optionalWords: [String]
