## Chain Middleware to Create a Time Server
<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds -->
Similar to the last challenge, but now we are chaining 2 functions together. It seems complicated, but it's just javascript.
Instead of responding with the time we can also add a string to the request and pass it to the next function. This is trivial, but it makes for a decent example. The code looks like:
```javascript
app.get("/now", middleware(req, res, next) {
req.string = "example";
next();
},
function (req, res) {
res.send(req.string); // This will display "example" to the user
});
```

## Get Data from POST Requests
<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds -->
Just like using req.query we can do req.body to get our data. This challenge is very similar to "Get Query Parameter Input from the Client."
In order to get data from a post request a general format is:
```javascript
app.post(PATH, function(req, res) {
// Handle the data in the request
});
```

If someone tells you to build a GET or POST you would do app.get(...) or app.post(...) accordingly. The basic structure of the challenge is:
```javascript
app.get("/:word/echo", function(req, res) {
// word = req.params.word;

## Implement a Root-Level Request Logger Middleware
<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds -->
It is easier to write this challenge all at the top (there is already a stub for it). This is because middleware must be placed the function calls you want it to be used for.
To set up your own middleware you can do it like so:
```javascript
app.use(function middleware(req, res, next) {
// Do something
// Call the next function in line:
next();
});
```
If you have trouble formatting the string correctly, one way to do it looks like:
```javascript
var string = req.method + ' ' + req.path + ' - ' + req.ip;
```

## Meet the Node console
<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds -->
Make sure you have cloned the correct repository/glitch project and are writing your code in myapp.js.
There are many methods available from the node console. You can find a list of these methods with Node.js documentation
<a href='https://nodejs.org/dist/latest-v10.x/docs/api/console.html' target='_blank' rel='nofollow'>here</a>. A common use would be to log errors such as:
```javascript
console.log("An error happened");
```
### If you use Glitch
- Glitch had changed the 'Logs' button to 'Status' button, still on the top-left, under the app name
- Don't submit the 'Edit' page directly. Click the 'Show' button (on top) and submit the application show page's url (url format is like https://appname.glitch.me/)

## Serve an HTML File
<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds -->
You probably need to comment out the last challenge. If you have a website and want to serve an index.html file you probably want to put this in a public folder. This is to ensure the public doesn't see something you dont want them to, and it sometimes is called "public" or "views," but you can technically call it whatever you want.
To serve an index.html in a folder called "public" at the root domain you would do so like this:
```javascript
app.get("/", function(req, res) {
res.sendFile( __dirname + "/public/index.html");
});
```
Note: __dirname returns the root directory is a best practice for node developers.

It is rather simple to serve a json object with node (at the '/json' route), if we want to deliver a message and give it the value "Hello World," we can do so like this:
```javascript
app.get("/json", function(req, res) {
res.json({"message": "Hello World"});

<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds -->
Static webpages are fairly simple with express. This could be useful for building your own portfolio website or blog, etc.
To serve a static webpage from the "views" folder you can use code such as:
```javascript
const express = require("express");
const app = express();
app.use(express.static(__dirname + "/views"));
```

If you had a website at "example.com/" and wanted to serve a string such as "Hello World" to whoever visits the root domain you could do so easily using node and/or express:
```javascript
app.get("/", function(req, res) {
res.send("Hello World");
});
```
Also, with ES6+ you can save some typing by using "=>" instead of "function," which looks like:
```javascript
app.get("/", (req, res) => {
res.send("Hello World");
});
```

The body-parser should already be added to your project if you used the provided boilerplate, but if not it should be there as:
```code
"dependencies": {
"body-parser": "^1.4.3",
...

You need to do for this challenge is pass the middleware to app.use(). Make sure it comes before the paths it needs to be used on.

We can use the .toUpperCase() method to make a string all caps, such as:

var response = "Hello World".toUpperCase(); // now becomes "HELLO WORLD"
```
All we need to do now is check what the value of the environment variable is, which you can do like:

resonse = "Hello World".toUpperCase();
} else {
response = "Hello World";
}

## Chain Search Query Helpers to Narrow Search Results
1. To create but not execut a find query
```javascript
Model.find( {name: 'Leah'} )
```
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
2. To store the find query into a variable for later use:
```javascript
var findQuery = YourModel.find( {name: 'Leah'} )
```
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
3. To sort an array:<br>
```javascript
yourArray.sort( {age: 1} ) // Here: 1 for ascending order and -1 for descending order.
```
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
4. To limit an array's size:
```javascript
yourArray.limit(5) // return array which has 5 items in it.
```
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
5. To hide certain property from the result:
```javascript
yourArray.select( {name: 0, age: 1} ) // Here: 0 means false and thus hide name property; 1 means true so age property will show.
```
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
6. To exec this query, you can either:</br>
&nbsp;&nbsp;1) Callback:
```javascript
YourQuery.exec(function(err, docs) {
//do something here
})
```
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Or 2) Promise
```javascript
YourQuery.exec.then(function(err, docs) {
//do something here
})
```
7. Chain it all together:
```javascript
Person.find({age: 55}).sort({name: -1}).limit(5).select( {favoriteFoods: 0} ).exec(function(error, people) {
//do something here
})
```
</br>
