Web app that takes a text file and finds the top K most frequent words.

• Java 17
• Spring Boot 3

cd top-k-words
./gradlew clean build

cd top-k-words
./gradlew run

Postman could be used for friendly UI, but the instuctions are provided for CURL just to make testing simple 🙃

curl -X GET http://localhost:8080/

The only credentials allowed are

• email: [email protected]
• password: test

curl -X POST http://localhost:8080/auth/login \
    -H 'Content-Type: application/json' \
    -d '{"email":"[email protected]","password":"test"}'

The responce should be in the following format:

{"token":"JWT_TOKEN"}

curl -X POST http://localhost:8080/api/topk/analyze \
    -F "[email protected]" -F "k=10" \
    -H "Authorization: Bearer JWT_TOKEN"

Feel free to experiment with the file content and K parameter.

3 sec delay was added to the file analysis to demonstrate caching impact on the app performance! Call /api/topk/analyze endpoint second time with the same parameters (same K value and same file content) to test caching.
