Get a user by their ID API [GET request]

Get a user by their ID API [GET request]

If validation.success is false we just go back many techniques from the recognition and provide they to your consumer with a status signal of 400 .

Once our recognition is in location and in addition we know the data we have been acquiring is good, after that we perform some utilizing:

After that we destruct firstName, lastName, means from req.body and move those beliefs to your UserModel.createUser . If anything happens right, it merely returns achievements: true with all the new user developed along side a status 200 .

Very all the audience is performing let me reveal adding a fixed approach to all of our userSchema also known as createUser that takes in 3 details: firstName, lastName, sort .

Right here the this role is vital, since we’re creating a fixed way on userSchema . Composing this will make sure our company is using carrying out businesses on the userSchema object

A very important factor to notice here’s that userSchema.statics.createUser = async purpose (firstName, lastName, means) => <> don’t work. When you use an => arrow function the this context will be destroyed and it won’t run.

When you need to find out about static practices in mongoose, see this very short but useful doctor instance here.

Now that we now have anything setup, let’s start our very own terminal by running listed here demand within the task’s underlying folder:

You could have the whole postman API collection from this point so that you don’t need to write the APIs over repeatedly.

Awesome a€“ we just ended up creating our very own first API. Let’s write one or two even more individual APIs before we move to the chat part since there is no talk without customers (unless we’ve robots, but robots include users at the same time ?).

Next we need to compose an API that will get all of us a person by the ID. So for our course .get(‘/:id’, user why don’t we take note of their operator.

We go in an id factor and in addition we wrap the function in try/catch . This will be significant while you are using async/await . The contours to pay attention to here are these 2:

We need mongoose ‘s findOne way to find an entry by id . We realize that one product is available into the range through this id because id is special. If no user is found we simply put one using the message No consumer with this id discovered .

See all users API [GET consult]

Next why don’t we produce the static method for getUsers() from inside the models/User.js file. Beneath the finally fixed method you authored for the reason that file, type:

We use the mongoose means also known as await this.find(); to get all documents in regards to our consumers range and return it.

Note: I’m not handling pagination within customers API for the reason that it’s not the main focus right here. I’ll speak about pagination as we push towards the cam APIs.

Delete a user by ID API [DELETE request] (a lot more of a bonus area, you’ll miss this if you like)

Let us establish our very own best approach to delete a person by their unique ID. The route .delete(‘/:id’, user.onDeleteUserById) choose its controller in controllers/user.js and create this code when you look at the onDeleteUserById() way:

We move inside the id here as a factor and then make use of the mongoose strategy also known as this.remove to remove an archive item from a particular collection. In cases like this, oahu is the users collection.

Next we will manage just how to authenticate routes with an authentication token. This is basically the last thing I would like to mention before moving forward with the cam area a€“ because every one of the chat APIs can be authenticated.

What are middlewares in ExpressJS?

Returning to the rule base, let’s generate a JWT middleware to authenticate all of our tracks. Go to middlewares/jwt.js and add the annotated following:
