Node.js an open-source JavaScript run-time environment. There are hundreds of interesting open source Node projects we sometimes highlight in our regular JS digest. But some of them so neat that we make separate materials about them. Like today. Nexe is a command-line utility to compile Node.js apps that you probably didn’t hear before. 

By default nexe will attempt to download a pre-built executable. However, It may be unavailable or you may want to customize what is built. You will also need to ensure your environment is set up to build node. Keep in mind, that the python binary in your path should be an acceptable version of python 2. eg. Systems that have python2 will need to create a symlink.
