I have the following Array:
const cars = [
{ make: 'Toyota', model: '4Runner', bodyType: 'SUV' },
{ make: 'Audi', model: 'A4', bodyType: 'Sedan' },
{ make: 'Ford', model: 'F-150', bodyType: 'Truck' },
]
I would like to send the cars array when visiting /cars endpoint. But when the user adds a query to the endpoint such as /cars?bodyType=SUV it should only return the filtered items.
So far I have:
app.get('/cars', (req, res) => {
const bodyType = req.query.bodyType
const filteredCars = cars.filter((car) => car.bodyType === bodyType)
res.send(req.query === ? cars : filteredCars)
})
I know i'm probably way off.
The following code works loops through all the keys in the query and compares it with the car object.
app.get('/', (req, res) => {
const filter = req.query
const haveFilters = Object.keys(filter).length
let filteredCars = cars
if(haveFilters){
filteredCars = cars.filter((car) => {
for(let key in filter){
if(car[key] !== filter[key]) return false
}
return true
})
}
res.send(filteredCars)
})
