body-parser VS Nodemon.io

Using body-parser you can set the limit on the size of the payload

body-parser is a middleware that parses the body of incoming requests, and exposes the resulting object on req.body

Now that our app can send us messages, can we send messages back to it? Let's implement the slash command, which will allow us to ask our app for some of its important stats and info. This time, Slack will send an HTTP POST to our app. If we take a look at the Slack docs again, we notice that Slack will send the slash command instruction to the URL we specified in the command set up earlier. We can also see that the POST payload is in the format application/x-www-form-urlencoded. We can set up a body-parser to interpret this data.

Our server application is a very simple one. We just render a simple HTML page with a form and input field to search for the user name. And we are using pug as our template engine for the express app and the body-parser library which is Node.js body parsing middleware to parse incoming request bodies in a middleware before your handlers, available under the req.body property.

nodemon - enables automatic reload of your server after code change docs

Then, install nodemon (in the VSCode terminal also), which, to my understanding, automatically refreshes the server you'll be sending requests to, whenever you make a change. Using plain node.js, you'd have to manually stop and restart the server after every change.

That's already pretty good, but as you already know it's a PITA to work with this during development. You will have to rebuild your Docker images whenever you change your code, even though your apps will probably support hot-reloading out of the box (or with something like Nodemon if not).

Are you moving your projects to use ES Modules but you are facing some unexpected issues? You are not alone in this fight. In this tutorial, you will learn how to set up nodemon along with ts-node.

We can now use npm run dev to start the server using nodemon, which enables hot refreshing on changes.

Welcome to my blog, where we dive into the intriguing world of Node.js development and tackle one of the common stumbling blocks many developers encounter: the "Nodemon Error - nodemon.ps1 cannot be loaded because running scripts is disabled on this system." If you've ever come across this error while working with Nodemon, fear not! In this article, we will explore the causes behind this issue, understand why scripts are disabled on certain systems and most importantly, provide you with practical solutions to overcome this obstacle and keep your development workflow seamless. So, let's embark on this troubleshooting journey together and empower ourselves to conquer the Nodemon Error!

You’ll need to restart the server using node index.js whenever you change any project file. You can also use Nodemon to automate this.

nodemon will be required to monitor for any changes in our source code and automatically restart our server.
