Since Chrome apps are now being deprecated. Download postman from https://dl.pstmn.io/download/latest/linux

Although I highly recommend using a snap

sudo snap install postman

Installing Postman

tar -xzf Postman-linux-x64-5.3.2.tar.gz

Developing with Node, without installing node!

Note: currently only works on *nix systems (until a powershell script can be created)

With the technique below, you can run node, npm, npx, or yarn commands as if the programs were installed natively on your system, and you won't even know the difference! This includes any ports that your app or dev process will start up and use for development, as well as compatibility with persistent npm config --global cli usage.

See more in the Usage section below.
