[discussion] Express server and how it should look

[SirrorsMoore1975]

Objective

• [ ] client: create axios request for signin, signup to the server
• [ ] server: send response from server to client

 // short hand version is axios.post('./login', {theEmail: email, thePassword: password })
        axios({
             method: "post",
             url: "/login",
             data: {theEmail: email, thePassword: password}
         }).then((response) => {
             console.log(response);
           }, (error) => {
             console.log(error);
           });

shorthand will be less stressful

// payload you sending via /user
const response = axios.post('/user', payload);
// response from server
const result = response.data

Server Side

Tips: Use postman to run the endpiont to check if your endpoints run as expected

1. Get method - should do something and return detail when the client send this
2. Post method

get method example:

1. Example

   app.get('/users', (req, res)=>{ 
   // Do a default action when this is called, to do what, you decide
   // return by res.send(thePayloadYouWantedToSend)
   // It can send query by /users?variable1=info1&variable2=info2
   const query = req.query.limit;
   const variable1 = req.query.variable1;
   const variable2 = req.query.variable2;
   })

2. Example

   app.get('/users/:id', (req, res)=>{
   /*
   *   received from: req.params.id
   *   send payload to: res.send(datasendback)
   */
   const id = req.params.id
   res.send(dataSendBack)
   });

   post method example:

3. Example

   app.post('/users', (req, res)=> {
   // data from client is enbed into body, and it is an object
   const user = req.body;
   
   // data send back to client, let client know what happended
   res.send(dataSendBack)
   } )

4. Example

   app.post('/users/:id', (req, res) =>{
   const id = req.params.id
   res.send(dataSendBack)
   })

put method example

1. Example

   app.put('/users/:id', (req, res)=> {
   let user = req.body; // what is expected is to update user
   const id = req.params.id
   res.send(dataSendBack)
   })

delete method example

app.delete('/user/:id', (req, res) => {
let id = req.params.id // expecting user id to be deleted, likely in the usertable
res.send(dataSendBack)
})

Knex

db('tablename')
.select({id:"id",username:"username", email:"email", address:"address"})
.from('tablename') // ?????
.limit(max)
.timeout(1500)
.where("provider_id", provider_id_variable)
.orderBy('id','desc')
.select(*)
