REST_API_TUTORIAL

How To Run

First of all you need to initialize a database by running

python3 init_db.py

This creates a database.db with 6 records.

Start the flask application

export FLASK_APP=prog_lang_app.py

flask run -p <port number>

You can now work with the small programming language database as follow.

This is the command to get all existing programming languages:

curl -X GET http://127.0.0.1:5001/programming_languages

This is the command to create a new programming language:

curl -X POST http://127.0.0.1:5001/programming_languages 
-H 'Content-Type: application/json' 
-d '{"name": "Java", "publication_year": 1995, "contribution": "Object-oriented programming language."}'

This is the command to update an existing programming language:

curl -X PUT http://127.0.0.1:5001/programming_languages/Java 
-H 'Content-Type: application/json' 
-d '{"contribution": "The JVM"}'

This is the command to delete a programming language:

curl -X DELETE http://127.0.0.1:5001/programming_languages/COBOL

To be Implemented in the Future

• create nice project architecture
• create front end
• create ci/cd piepline (read data from other sources and insert into the database)
• see what else we can learn when implementing rest ful API
