SplatNet 3 types

TypeScript types for SplatNet 3 and splatoon3.ink.

Usage

Types for each GraphQL query are exported from splatnet3-types/splatnet3 and splatnet3-types/graphql/....

• Current persisted query IDs are available in RequestId.
• Result types are available using ResultTypes and as named types (e.g. HomeResult).
• Variable types are available using VariablesTypes and as named types (e.g. HomeVariables).

import { StageScheduleResult } from 'splatnet3-types/splatnet3';
// or
import { RequestId, ResultTypes } from 'splatnet3-types/splatnet3';
type StageScheduleResult = ResultTypes[RequestId.StageScheduleQuery];
// or a specific version
import StageScheduleQuery_df9738c from 'splatnet3-types/graphql/df9738cb0fbd533a888feaf21f1e2b14';
// or
import { ResultTypes } from 'splatnet3-types/splatnet3';
type StageScheduleQuery_df9738c = ResultTypes['df9738cb0fbd533a888feaf21f1e2b14'];

declare const schedules: StageScheduleResult;

Types for using all versions of a query can be used with RequestIds:

type SavedVsHistoryDetail = {
    [Id in RequestIds<'VsHistoryDetailQuery'>]: {
        result: ResultType<Id>['vsHistoryDetail'];
        query: Id;
    };
}[RequestIds<'VsHistoryDetailQuery'>];

const data: SavedVsHistoryDetail;

// data.result is a VsHistoryDetailQuery_9ee0099 | VsHistoryDetailQuery_291295a | ...
// data query is a '9ee0099fbe3d8db2a838a75cf42856dd' | '291295ad311b99a6288fc95a5c4cb2d2' | ...

if (data.query === '9ee0099fbe3d8db2a838a75cf42856dd') {
    // data.result is a VsHistoryDetailQuery_9ee0099
}
if (data.query === '291295ad311b99a6288fc95a5c4cb2d2') {
    // data.result is a VsHistoryDetailQuery_291295a
}

Additional types for the SplatNet 3 GraphQL API are also exported from splatnet3-types/splatnet3.

import {
    GraphQLError, GraphQLErrorResponse, GraphQLRequest, GraphQLResponse, GraphQLSuccessResponse,
    RequestId, ResultTypes, VariablesTypes,
} from 'splatnet3-types/splatnet3';

const request_data: GraphQLRequest<VariablesTypes[RequestId.HomeQuery]> = {
    // ...
};

const response = await fetch('https://api.lp1.av5ja.srv.nintendo.net/api/graphql', {
    body: JSON.stringify(request_data),
    // ...
});

const data: GraphQLResponse<ResultTypes[RequestId.HomeQuery]> = await response.json();

if (data.errors) {
    // data is a GraphQLSuccessResponse<ResultTypes[RequestId.HomeQuery]> with an errors property
    // or a GraphQLErrorResponse

    // data.errors is an array of GraphQLError objects
} else {
    // data is a GraphQLSuccessResponse<ResultTypes[RequestId.HomeQuery]> (without an errors property)
}

Splatoon3.ink types

Types for Splatoon3.ink data are exported from splatnet3-types/splatoon3ink.

import { Coop, Festivals, Gear, Schedules } from 'splatnet3-types/splatoon3ink';

const schedules: Schedules = await fetch('https://splatoon3.ink/data/schedules.json').then(r => r.json());
const gear: Gear = await fetch('https://splatoon3.ink/data/gear.json').then(r => r.json());
const coop: Coop = await fetch('https://splatoon3.ink/data/coop.json').then(r => r.json());
const festivals: Festivals = await fetch('https://splatoon3.ink/data/festivals.json').then(r => r.json());

TypeScript configuration

splatnet3-types uses the package.json exports field. TypeScript must use node16 (or nodenext) module resolution to resolve imports correctly.

{
    "compilerOptions": {
        "moduleResolution": "node16"
    }
}

This option cannot be used with Next.js as it doesn't support JavaScript modules natively. As a workaround types can be imported using relative paths:

import '../node_modules/splatnet3-types/dist/splatnet3.js'; // instead of splatnet3-types/splatnet3
import '../node_modules/splatnet3-types/dist/splatoon3ink.js'; // instead of splatnet3-types/splatoon3ink
import '../node_modules/splatnet3-types/dist/generated/queries/....js'; // instead of splatnet3-types/graphql/...

Structure

• Types for GraphQL requests in the SplatNet 3 web app are stored in src/generated. These are generated automatically from metadata used by Relay in the app's JS bundle.
• These use the types defined in src/types.ts. This file essentially defines the GraphQL schema and is required for correct scalar and null types. Enum values are defined in src/enum.ts.
  • These types are exported but should not be used directly as they will not be returned from the GraphQL API.
• Partial/fragment types for some fields are defined in src/partial-types.ts. These are only available for the latest query versions.
• Types for request variables are defined in src/variable-types.ts.
• Some helper types, the current version of each query, and links to variable/result types are defined in src/graphql.ts.
