Gradient Edge commercetools utils

An easy-to-use toolkit for working with the commercetools HTTP API: https://docs.commercetools.com/api/

Please note: this API is being built out bit by bit. If you're looking to use a method that doesn't appear to exist, please either raise an issue or feel free to make the change yourself and raise a PR 👍

See full documentation here: API documentation.

How does this compare to the official commercetools SDK?

We think it's easier to use and less verbose. On the flip side, the official commercetools SDK is more flexible and certainly more complete and up to date.

Installation

Simply install the @gradientedge/commercetools-utils package using your package manager, e.g.:

npm install --save @gradientedge/commercetools-utils

Code examples

For clarity, we use the term grant to describe the object that holds the access token, refresh token, scope and expiry details.

Creating a client grant

import { Region, CommercetoolsAuth, CommercetoolsGrant } from '@gradientedge/commercetools-utils'

async function example() {
  const auth = new CommercetoolsAuth({
    projectKey: 'your-project-key',
    clientId: 'your-client-id',
    clientSecret: 'your-client-secret',
    region: Region.EUROPE_GCP,
    clientScopes: ['create_anonymous_token']
  })

  let grant: CommercetoolsGrant

  try {
    const grant = await auth.getClientGrant()
    console.log('Grant:', grant)
  } catch (error) {
    // 'error' will likely be an instance of CommercetoolsError.
    // See the API for full details.
    console.error(error)
    throw error
  }
}

Logging in a customer

import { Region, CommercetoolsAuth, CommercetoolsGrant } from '@gradientedge/commercetools-utils'

async function example() {
  const auth = new CommercetoolsAuth({
    projectKey: 'your-project-key',
    clientId: 'your-client-id',
    clientSecret: 'your-client-secret',
    region: Region.EUROPE_GCP,
    clientScopes: ['create_anonymous_token']
  })

  let grant: CommercetoolsGrant

  try {
    const grant = await auth.login({
      username: 'myUsername',
      password: 'myPassword'
    })
    console.log('Grant:', grant)
  } catch (error) {
    console.error(error)
    throw error
  }
}

example()

Note that the getClientGrant method here could be swapped out for say, login, in order to login a customer. There is no need to call getClientGrant before calling login. Ensuring that there's an active client grant will be taken care of by the CommercetoolsAuth class.

Get an anonymous customer grant

import { Region, CommercetoolsAuth, CommercetoolsGrant } from '@gradientedge/commercetools-utils'

async function example() {
  const auth = new CommercetoolsAuth({
    projectKey: 'your-project-key',
    clientId: 'your-client-id',
    clientSecret: 'your-client-secret',
    region: Region.EUROPE_GCP,
    clientScopes: ['create_anonymous_token']
  })

  let grant: CommercetoolsGrant

  try {
    const grant = await auth.getAnonymousGrant()
    console.log('Grant:', grant)
  } catch (error) {
    console.error(error)
    throw error
  }
}

Refresh an existing customer grant

The code below demonstrates how we can call the refreshCustomerGrant method with the refreshToken of an existing grant. Realistically, that grant would probably have come from something like a JWT that was passed to your back-end server by your UI.

import { Region, CommercetoolsAuth, CommercetoolsGrant } from '@gradientedge/commercetools-utils'

async function example() {
  const auth = new CommercetoolsAuth({
    projectKey: 'your-project-key',
    clientId: 'your-client-id',
    clientSecret: 'your-client-secret',
    region: Region.EUROPE_GCP,
    clientScopes: ['create_anonymous_token']
  })

  let grant: CommercetoolsGrant

  try {
    const grant = await auth.login({
      username: 'myUsername',
      password: 'myPassword'
    })
    console.log('Grant:', grant)
  } catch (error) {
    console.error(error)
    throw error
  }

  // The 'grant' would have been
  const refreshToken = grant.refreshToken
  try {
    const grant = await auth.refreshCustomerGrant(refreshToken)
    console.log('Refreshed grant:', grant)
  } catch (error) {
    console.error(error)
    throw error
  }
}
