Dependencies
- It is important to use @babel packages because we use ES2015+ sintax on our code.
- Also, it is important to use body-parser to handle with post action.
express().use(bodyParser.json())and to get a value, just useapp.post('/', (req, res) => res.send(${req.body.name}!)) - To get value from params, use
express.get('/:value', (req, res) => res.send(${req.params.vale}!))when you need to pass by url. - Use
nodemonif you dont restart server every time you made a change. - Use
mongodbto handle with database and useMongoClientto connect.
Why MongoDB?
- Non relational database
- Can push data to database without worrying about format (accepts any JSON object)
- Strucuture of data does not have be defined in advance
- SQL not required
Start mongo:
mongod
Access mongo:
mongo
Create database:
use my-database
Add data:
db.posts.insert([{...}])
Consult data:
db.posts.find({})
Consult data (formated):
db.posts.find({}).pretty()
Search data:
db.posts.find({name: 'post-name'}).pretty()
Search data (only one result):
db.posts.findOne({name: 'post-name'}).pretty()
- When you want to update some info on db, use
updateOnewith$setas first property of second argument.
