Purchase Ack Service

Repo Purpose

Expose a GraphQL API to MongoDB collection called purchaseorder-ack-details

• Responsible for purchase order domain in zoro system (previously was coupled with order document aka sales orders)
• GraphQL mutation to add ackDetails to mongo collection
• GraphQL query to fetch ackDetails from mongo collection
• Publishes SNS message to purchaseAck-sap-integration-service after successful mutation to ackDetails. purchaseAck-sap-integration-service downstream updates SAP with PO updates.

To play around with queries & mutations npm start and visit the graphql explorer localhost/4001/graphql

Setup

WITHOUT Vault

1. Copy config.json.example to config.json

WITH Vault

1. Copy token from vault dashboard (https://vault.zorouk.co.uk/) by clicking the arrow on the right-top corner of you dashbaord, you will have an option there called Copy token
2. Once you have your token copied to your clipboard, go in your IDE config.json file and in there you only need two object keys (vaultToken, secretPath). The vaultToken is the token that you have copied previously and api-services secret path should be: /local/dev.name/data/dev/ecs/api-services
3. Ensure npm run vault scripts contains vault ZORO_CONFIG_SRC=VAULT the env is used as flag to read local secrets from vault.

Once you have added a your config.json file in your project as in the following example, everything should work normally (as before):

{
   "vaultToken": "token",
   "secretPath": "/dev/data/dev/lambda/subscription-service"
 }
