The API_Names project is an API designed to find a name and its possible variations from a given name, and correct any misspellings. It uses the Metaphone (br) algorithm to search the database and the Levenshtein distance method for correction.

• JWT Authentication
• Limited access by Token
• Sign-up
• Login
• Log local and imported to the database from time to time
• Middleware

Before running the API, make sure you have MySQL installed on your machine.

1. Clone the repository
2. Create a .env file at the root of your project and set the following environment variables:

DB_USERNAME=<your_username>
DB_PASSWORD=<your_password>
DB_NAME=<your_database_name>
DB_HOST=<your_database_host>
DB_PORT=<your_database_port>
SECRET=<your_jwt_secret>

Replace the values with your own database credentials and a secret for JWT token generation. Worht to mention that the DB_NAME does not require an existing database.

3. Finally, run the API using the following command:

go run main.go

On the first run, the prompt will return:

go run main.go
2023/04/12 18:48:48 -   Created Database
2023/04/12 18:48:48 -   Upload data start
2023/04/12 18:49:21 -   Upload data finished 33.113701109s
2023/04/12 18:49:21 -   Created first user
2023/04/12 18:49:21 -   Listening and serving...

The main endpoint for the API is http://localhost:8080/metaphone/:name. You need to log in to get an access token before you can access any other endpoint.

The following table shows the available endpoints, their corresponding HTTP methods, and a brief description:
