The pipeline should reflect the following steps: Keep in mind that the app already has a command to enable live reload which is npm run dev:watch. If you have Node.js installed, go to the nodejs-with-mongodb-api-example folder and run the following commands: npm iĪfter running these commands, you can go to a browser on and see the application running as shown in the image below: The README.md file says that you need a MongoDB instance running before starting your app, along with Node.js. If you see the error, run docker rm mongodb and it will remove any previous instance so you can run the docker run command again. Notice that if you already have an instance with this name it'll throw an error about invalid name.

Using the command above, it'll download and run the MongoDB instance.

You'll also expose it on localhost:27017 so applications that are not running through Docker can access it without knowing the internal Docker IP address.Ĭopy the command below and paste it in your terminal: docker run -name mongodb -p 27017:27017 -d mongo:4

Instead of installing MongoDB on your local environment machine, you'll install it using Docker. It requires Node.js version 10 or higher and MongoDB.

If you take a look at the README.md file, there are a few instructions demonstrating how to run this app as shown in the image below:

Secondly, let's analyse what the application requires. Go to the Github repository and clone it on your post-docker-live-reload folder. Getting startedįirst, you'll need to have an empty folder called post-docker-livereload which you'll use as a workspace. So you don't need to go back and forth, restarting your app or even rebuilding the system.

Also, if you've never heard about live-reload (or hot reload), it is a feature that watches for changes in your code and restarts the server if needed. The best environment in my opinion should be:įollowing these principles, we'll configure an application over the next sections of this article. How would you do it? Do you know every dependency your app requires to work? What should a development environment look like?ĭevelopers have always tried to be more productive by adding plugins, boilerplates, and codebases on their editors/IDEs/terminals. Let's say you have decided to move from Windows Servers to Unix servers. We should work on new stuff, but also make improvements to existing applications. But what about legacy applications? Should we just rewrite everything with new tech? I know this is not as simple as it seems. It has given me the power to not only move applications through different environments, but also to keep my local environment as clean as possible.ĭevelopers working with cutting-edge technologies are always working with something new. So developers created Docker to help reduce the chances of possible errors.ĭocker is one of my favorite tools that I work with every day on desktop, web, and IoT apps. They're stable, and they're fun to develop and release, but they're not predictable when working over different environments. More and more cutting-edge technologies are being released for the internet all the time. Before starting to code make sure you have the following tools installed on your machine: In the next steps, you'll clone an existing project to execute all examples in this article. Aggregate all services within docker-compose.Enable live-reload by using docker volumes.Enable dependency caching on Node.js modules.Convert a legacy application to run within a Docker container.In this article, our goal is to tackle this mindset by demonstrating how simple configurations can result in many benefits such as a reliable environment over production and development environments.īy the end of this post you will have learned how to: They say that Docker isn't good for development because it always needs to rebuild the entire image to reflect all new modifications.

Some developers turn up their noses when talking about using Docker for their development environment. This will allow you to convert a legacy application so it uses Docker, Docker volumes, and docker-compose. In this post you'll learn how to configure a development environment with live-reload enabled.
