I want to get the shop if shop does not exist then call app.post() to add a new shop.
My app.post() it creates the shop successfully:
app.post('/shops/addShop', (req, res) => {
const shop = {
id: 'shop' + (shops.length + 1),
name: req.body.name,
departmentList: [
{
id: 'd1',
name: "department 1"
},
{
id: 'd2',
name: "department 2"
},
{
id: 'd3',
name: "department 3"
}
]
};
shops.push(shop);
res.send(shop);
});
How to implement getShop() by Id if exist otherwise create it by using app.post():
app.get('/shops/:id', (req, res) => {
// how to code here
});
You shouldn't call app.post() directly, that's an API controller, instead you want to have a separate function that performs this logic.
app.post('/shops', (req, res) => {
res.send(createNewShop());
});
app.get('/shops/:id', (req, res) => {
const shopExists = findShop(req.params.id);
if (!shopExists) {
return res.send(createNewShop());
} else {
// do something with your shop
}
});
