Node express params

Express js params

app.get('/path/:name', function(req, res) { // url: /path/test
  console.log(req.params.name);  // result: test
});

// OR

app.get('/path', function(req, res) {  // url: /path?name='test'
  console.log(req.query['name']);  // result: test
});

Express get params after ?

GET /something?color1=red&color2=blue

app.get('/something', (req, res) => {
    req.query.color1 === 'red'  // true
    req.query.color2 === 'blue' // true
})

req.params refers to items with a ':' in the URL and req.query refers to items associated with the '?

Node express params

// url = /something/2?color1=red&color2=blue&type=square

app.get('/something/:id', (req, res) => {
  	req.params.id  === 2 // true
    req.query.color1 === 'red'  // true
    req.query.color2 === 'blue' // true
    req.query.type === 'square' // true
})
