api-querier

A simple wrapper around axios to work with remote API resources as though they were local

Installation

This is an NPM package. It can be used with any of your favourite JavaScript/Typescript frameworks, anywhere axios runs

npm install --save api-querier

Usage

This package provides two entities that you could use in your code. It exports, by default, a function that can make an ApiQuerier object.

        import { makeApiQuerier, IApiQuerier, IResourceQuerier} from 'api-querier';

        const resourceNames = ['books', 'tables', 'pens'];
        const baseURL = 'https://your_api_base_url.com';
        // Put the baseUrl of your api without trailing slash
        /*
        * In this example, the endpoints exposed by the remote API are
        *   - https://your_api_base_url.com/books
        *   - https://your_api_base_url.com/tables
        *   - https://your_api_base_url.com/pens
        */

        const apiQuerier: IApiQuerier = makeApiQuerier(resourceNames, baseURL,
        /*{...headers}, customResourceProcessorFunction // if you wish to have a different one
                                                        // but there is surely no need
         */);
        // apiQuerier is object whose keys are the resource names while
        // the values are IResourceQuerier objects

        const booksQuerier = apiQuerier['books'];
        const tablesQuerier = apiQuerier['tables'];
        const pensQuerier = apiQuerier['pens'];
        // signature of each individual querier /
        /*
        *interface IResourceQuerier {
            list: (queryObj?: any, headers?: any) => Promise<AxiosPromise<any>>;
            getOne: (id: string | number, headers?: any) => Promise<AxiosPromise<any>>;
            update: ((id: string | number, payload: any, headers?: any) =>
                     Promise<AxiosPromise<any>>);
            create: (payload: any, headers?: any) => Promise<AxiosPromise<any>>;
            destroy: (id: string | number, headers?: any) => Promise<AxiosPromise<any>>;
          }
        *
        */
       // each ResourceQuerier can list, getOne, update, destroy, create its items
       // each returning the same data an axios call would return; whose data is on
       // response.data

       const someAsyncFunction = () => {

         // list and filter books
         const booksQueryParams = {
           author: 'Some Name'
         };
         const someHeadersIfYouWant = {
           Authorization: 'Bearer some_token',
           'Content-Type': 'application/json',
         };
         const allBooksAuthoredBySomeName = await booksQuerier.list(booksQueryParams,
               someHeadersIfYouWant);

         // getOne table
         const tableOfIdRandomString = await tablesQuerier.getOne('RandomString',
               /*{...extraHeaders}*/);

         // update table
         await tablesQuerier.update('RandomString', {legs: 2}, /*, {...extraHeaders}*/);
         const updatedTableOfIdRandomString = await tablesQuerier.getOne('RandomString',
               /*{...extraHeaders}*/);
         updatedTableOfIdRandomString.data.legs == 2; // true

         // delete table
         const response = await tablesQuerier.delete(
              'RandomString', /*, {...extraHeaders}*/);
         const responseAfterDelete = await tablesQuerier.getOne('RandomString',
               /*{...extraHeaders}*/);
        responseAfterDelete.status === 404; //true

       }
