The following application has been implemented in TypeScript as part of a dev quiz for the company SCHWABEO. The app provides a GET API endpoint under /evaluation which accepts the URLs of CSV files by specifing a url parameter. An example call would be:
http://localhost:3005/evaluation/?url=http://localhost:3005/csv/ps-1.csv&url=http://localhost:3005/csv/ps-2.csv
The CSV files are parsed and then evaluated. During the evaluation three questions are being answered:
- Which politician gave the most speeches in 2013?
- Which politician gave the most speeches on the topic 'Internal Security'?
- Which politician used the fewest words (in total)?
The answers are provided in JSON.
Install all dependencies by running the command npm install.
Under the hood the app uses dotenv to load environment variables via an .env file. Rename .env.example to .env to make the app load the provided env variables. The default server port is 3005.
To run the dev version of the app use the command npm run dev. The server will automatically restart once code changes are detected.
You can build and then run the app with the command npm run start. If you only want to build the production version use npm run build.
Run the integration and unit tests with npm run test. The API endpoint /evaluation is tested via an integration test, the functions in evaluation.js are tested by using unit tests. All test files can be found in the /__tests__ directory.
