This NestJS application processes 📊 .CSV files to aggregate tap data over specified intervals (daily 📅, weekly 📆, monthly 🗓️), returning the date range for each interval along with the total number of taps during that period. Access to the API requires an API key 🔑 associated with a team (team_id in data/interview-tags.csv). The association between API keys and teams is managed in src/auth/auth.service.ts. Note that the teamId used in requests must match a team_id in interview-tags.csv, and the Authorization header must contain a valid API key. The application uses nestjs/throttler to limit API users to 100 queries per hour ⏳.
Clone the repository and install dependencies:
git clone [email protected]:byennen/tap-data-service.git
cd tap-data-service
npm installStart the application in development mode:
npm run start:devRun tests:
npm run testBefore making requests, ensure you have a valid API key. Replace exampleKey1 in the curl commands with your actual API key.
curl --location 'localhost:3000/taps/aggregate?interval=day&start=2022-07-01&end=2022-07-31' \
--header 'Authorization: Bearer exampleKey1'curl --location 'localhost:3000/taps/aggregate?interval=week&start=2022-07-01&end=2022-07-31' \
--header 'Authorization: Bearer exampleKey1'curl --location 'localhost:3000/taps/aggregate?interval=month&start=2022-07-01&end=2022-07-31' \
--header 'Authorization: Bearer exampleKey1'Be mindful of common errors such as exceeding rate limits or providing invalid API keys. The API responds with appropriate HTTP status codes and messages to guide you in resolving such issues.
The API limits users to 100 queries per hour to ensure fair usage and system stability. Exceeding this limit will result in a 429 Too Many Requests response. It is advisable to implement retry mechanisms or handle this response gracefully in your client application.
