Data-normalization-service NPM

Digicust Data Normalization Service

Normalizes extracted data

Architecture

Business logic in src/service

Controllers (src/api/controller) are triggered by either service bus (src/api/service-bus) or express routers (src/api/routes)

Development & Deployment

Install Dependencies

npm i

Start Service

npm start

Testing Framework

We use Mocha and Chai with Chai-Http. This combination allows us to first start the server (load key vault values, start Express, ...) and then programmatically simulate requests.

Tests are coded in ./tests and allow for TypeScript.

npm test

Tests will automatically be processed with every Docker build (see Dockerfile)

Testing an Individual Case

You can test individual cases by pasting the case JSON (find it via https://support-tool.digicust.com/caseFetch) to /tests/test-data/dynamic.json

In tests/test.ts set it.skip("Dynamic Case", async function () to it.only

Then run

npm test

You will find the output in /tests/test-data/dynamic-output.json

In tests/test.ts set it.only("Dynamic Case", async function () back to it.skip
