Atom is a coding editor that was developed by Github. Because Github is now owned by Microsoft, Atom is technically maintained by Microsoft. And, sure, it is kept up to date. There are a lot of individuals on Github who are following the Atom repository, staring the repository, and actually using the editor.
A hackable text editor for the 21st Century
GitHub for Atom
A text editor is at the heart of a developer's toolkit, yet it hardly works alone. The GitHub package allows you to interact with Git and GitHub directly from Atom.
Create new branches, stage and commit them, push and pull them, handle merge conflicts, see pull requests, and more - all from your editor. The GitHub package is pre-installed with Atom, so you're good to go!
What is a "live server?"
Live Server that makes your existing server live - this is a Web Extension that helps you to live reload feature for dynamic content (PHP, Node.js, ASPNET - Whatever, it doesn't matter).
Go to Packages –> Settings View –> Install Packages/Theme screen allows for installing new ones.
In the “Search packages” text area or input field, type "atom-live-server" to find the package.
Click "Install" to download and install the atom-live-server package. (This process can take seconds to up to few minutes depending on bandwidth and other factors.)
Using a package called live server in atom.
Atom now includes a local web server thanks to the atom-live-server package.
Start:Click Packages –> atom-live-server –> Start server to launch the web-server for the currently open project (folder).
Stop: (Once launched, it may be terminated by going to Packages –> atom-live-server –> Stop...)
When atom-live-server is started, it launches a web server on port 3000 on the localhost. To put it another way, this is a private, local version of a web server.
Note: When hosting a web server on Windows, the Windows Defender Firewall may request you to confirm which sorts of networks to allow access to. Never use atom-live-server as a private server with public network access.
