occ-client v3

This package acts as a client for the SAP Commerce OCC that expose the API docs as an OpenAPI3.0 specification.

Creation of the client

Without client credentials

In case you don't need access token to be able to operate with the API, you can create the client directly.

import {OccClient} from '@e2y/occ-client';
import {paths} from '../../types/occ/schema';

const occClient = await new OccClient(
  new URL('https://localhost:9002/occ/v2/')
).create<paths>();

With client credentials

import {OccClient} from '@e2y/occ-client';
import {paths} from '../../types/occ/schema';

const occClient = await new OccClient(
  new URL('https://localhost:9002/occ/v2/'),
  {
    oauthTokenUrl: new URL(
      'https://localhost:9002/authorizationserver/oauth/token'
    ),
    clientId,
    clientSecret
  }
).create<paths>();

With password credentials

Depending on the actions you want to make, you may need to use the password grant type. To do so, you can use the password method.

import {OccClient} from '@e2y/occ-client';
import {paths} from '../../types/occ/schema';

const occClient = await new OccClient(
  new URL('https://localhost:9002/occ/v2/'),
  {
    oauthTokenUrl: new URL(
      'https://localhost:9002/authorizationserver/oauth/token'
    ),
    clientId,
    clientSecret,
    username,
    password
  }
).create<paths>();

Using the client

First, you need to specify the paths of the resources you want to use (refer to [Creating schema from OpenAPI3.0]( #creating- schema-from-openapi30)). In case of the OCC-Client, you do this once you instantiate the client.

import {OccClient} from '@e2y/occ-client';
// This are the paths you need to import
import {paths} from '../../types/occ/schema';

const occClient = await new OccClient(...).create<paths>()

Then, you create the endpoint you want to use.

const getCurrencies = fetcher
  .path('/{baseSiteId}/currencies')
  .method('get')
  .create();

Finally, you can use the endpoint to get the data you want.

const currenciesResponse = await getCurrencies({baseSiteId: 'wololo'});

Creating schema from OpenAPI3.0

You can create the schema of any API that meets the OpenAPI3.0 specification. To do so, you can use the schema package.

npx openapi-typescript https://myapi.dev/api/v1/openapi.yaml -o ./path/to/my/schema.d.ts

You can find more information about this here.

Using the OAuth2 Client

The OccClient uses the OAuth2Client class to handle the authentication. You can use it directly if you need to perform actions that are not covered by the OccClient.

import {OAuth2Client} from '@e2y/occ-client';

const oauth2Client = new OAuth2Client({
  oauthTokenUrl: new URL(
    'https://localhost:9002/authorizationserver/oauth/token'
  ),
  clientId,
  clientSecret,
  username,
  password
});

const {accessToken} = await oauth2Client.getToken();
