SachinApp

My app to learn basics of Docker, MongoDb, Python, Node.js, Testing, code coverage, Linting.

Creating App which

User can send usreName and text to save in Db (POST API)
User can get his text by UserName (GET API)
Can execute python code on jupyter kernelgateway

I save data in MongoDb, Creare APIs in Python and UI in Node.js. Each will run inside docker container.

Mongo Db

Commands For Docker

docker pull mongo
docker run -d -p 27017-27019:27017-27019 --name mongodb mongo
Learn Mongo DB - https://www.tutorialspoint.com/mongodb

Python APIs

python connets mongodb - https://www.w3schools.com/python/python_mongodb_create_db.asp
docker build python-api
docker run -p 5000:5000 -d --name python-api container_id

Node.js Front End APIs

npm install express --save (also do for ejs, body-parser, request etc.)
docker build nodejs-ui
docker run -p 3000:3000 --name nodejs-ui -d b00152f27a96

Linting

python - pylint *.py
node.js eslint
npm install eslint -g
eslint --init
eslint app.js --fix

Testing and Code coverage

nosetests --with-coverage
learn nosetests - https://nose.readthedocs.io/en/latest/finding_tests.html

Other imp stuff

releasing port if already useed sudo lsof -i:port kill -9 p_id
linking the containers - docker run -it --name python_container --link mongodb -d d609a386f707
post directly on python - curl -X POST 'http://0.0.0.0:5000/?userName=abc11&data=abcd'
