wikibase-rest-api-ts

Typescript model and API code for interacting with the REST API of a Wikibase instance (like Wikidata).

Usage

Read the official OpenAPI specification for the Wikibase REST API at this link. Depending on the tags of the method you want to use, initialize an object of the relevant API class and call the appropriate method:

AliasesApi
DescriptionsApi
ItemsApi
LabelsApi
PropertiesApi
SitelinksApi
StatementsApi

Example

Suppose you want to get the label of Wikidata item Q1 in english. From the OpenAPI specification you find out that the appropriate method is GET /entities/items/{item_id}/labels/{language_code}, under the tag labels (=> LabelsApi). You don't need to specify which instance to use because Wikidata is the default.

import { LabelsApi } from "wikibase-rest-api-ts";
const api = new LabelsApi();
api.getItemLabel({
        itemId: "Q1", languageCode: "en"
    }).then(
        label => console.log(`English label for Q1 is ${label}`)
    );

Custom instance

If instead of Wikidata you want to use another Wikibase instance you need to pass its REST API base URL while initializing the API:

import { Configuration, DescriptionsApi } from "wikibase-rest-api-ts";
const api = new DescriptionsApi(new Configuration({
        basePath: "https://url-to-my-wikibase-instance/w/rest.php/wikibase/v0",
    }));
api.getItemDescription({
        itemId: "Q1", languageCode: "en"
    }).then(
        desc => console.log(`English description for Q1 is ${desc}`)
    );

Authentication and write operations

If you need to upload changes to the data you will need first to create an OAuth access token following the instructions at this link. Then you will need to pass the Authorization header for each call:

import { Configuration, DescriptionsApi } from "wikibase-rest-api-ts";
const api = new DescriptionsApi(new Configuration({
        headers: { Authorization: "Bearer " + YOUR_TOKEN }
    }));
api.replaceItemDescription({
        itemId: "Qxxx",
        languageCode: "en",
        replaceItemDescriptionRequest: {
            description: "New description of the item",
            comment: "Comment of your edit"
        }
    });
