Work with colour values Converting colour values from one format into another is one of the tasks every frontend developer needs to do once in a while. TinyColor2 takes care of this programmatically, and it's available for Node.
It provides a set of conversion methods e. Working with different formats Then PDFKit is the module you are looking for.
It supports embedding font types, embedding images and the definition of vector graphics, either programmatically using a Canvas-like API or by specifying SVG paths. Furthermore, you can define links, include notes, highlight text and more. The best way to start is the interactive browser demo, which is available here.
ThenCheerio is the answer.
Although it implements only a subset of the core jQuery library, it makes processing HTML on the server side much easier. For example, Microsoft Excel allows you to export or import your data in that format. Process markdown files Markdown is a popular format when creating content for the web.
If you ever wanted to process markdown content programmatically i. It takes a string of markdown code as input and outputs the appropriate HTML code. It is even possible to further customise that HTML output by providing custom renderers. What are Routes? Routing refers for determining the way in which an application responds to a client request to a particular endpoint.
So based on the URL which is accessed, a different functionality on the web server will be invoked and accordingly the response will be sent to the client. This is the concept of routing. Each route can have one or more handler functions, which are executed when the route is matched. The general syntax for a route is shown below app.
How Does It Work?
Let's look at an example of how we can implement routes in express. The below snippet is an add-on to show case how routing is implemented.
To the route, we are attaching a callback function which will be called when we browse to the Node URL. The function has 2 parameters.
The main parameter we will be using is the 'res' parameter which can be used to send information back to the client. The 'req' parameter has information about the request being made. Sometimes additional parameters could be sent as part of the request being made, and hence the 'req' parameter can be used to find the additional parameters being sent.
We are using the send function to send the string "Tutorial on Node" back to the client if the Node route is chosen. To the route, we are attaching a callback function which will be called when we browse to the Angular URL.
We are using the send function to send the string "Tutorial on Angular" back to the client if the Angular route is chosen. When the default route is chosen, the message "Welcome to Guru99 Tutorials" will be sent to the client. If the command is executed successfully, the following Output will be shown when you run your code in the browser.
Output: From the output, You can clearly see that we if browse to the URL of localhost on port , you will see the string 'Welcome to Guru99 Tutorials' displayed on the page.
Building a Restful CRUD API with Node.js, Express and MongoDB
Because in our code, we have mentioned that our default URL would display this message. This sort of routing is what is used in most modern day web applications. The other part of a web server is about using templates in Node js. When creating quick on-the-fly Node applications, an easy and fast way is to use templates for the application.
There are many frameworks available in the market for making templates. In our case, we will take the example of the jade framework for templating.
14 Best NodeJS Frameworks for Developers in 2019
Jade gets installed via the Node Package manager. This can be done by executing the following line in the command line npm install jade The above command requests the Node package manager to download the required jade modules and install them accordingly. Instead use pug.
Let's use our newly installed jade framework and create some basic templates. Step 1 The first step is to create a jade template. Create a file called index.Sails is especially suitable for developing realtime features like chat.
On the server-side, we have a simple Express. Is Node.
It is also built on Express. Now that we know what we are going to build, We need a cool name for our application.
