+title: Change node version automatically with nvm and zsh

+
+I have been a zsh user for a while now, for those who do not know zsh, it is a unix shell and command language based on bash with improvements.
+Recently, I found myself with a very slow terminal. It took a good 3 to 5 seconds to launch a new terminal session in any directory, which got
+increasingly annoying. The major culprit was a bash script I nicked of stackoverflow 😅 (you know you do it too). I decided to remove that piece of
+code, write my own (hopefully a simple and improved version of it).
+
+### Let's modify the zsh profile
+
+```bash
+open ~/.zshrc
+```
+To begin, open your zshrc file located here `~/.zshrc` (this is platform dependent), in your favourite editor.
+
+We will be tapping into zsh hook functions to make this work, specifically `chpwd`, which is executed whenever the current working directory is
+changed.
+
+```bash
+chpwd_functions=(change_nvm_version)
+```
+
+Let's define the `change_node_version` function. We first check if the file exits with the `-f` flag, it also checks that `./.nvmrc` is nothing but a
+file. We `cat` the file and save the content in `$version`. Lastly, switch the node version with nvm (`nvm use $version`). I will assume you
+have `nvm` installed, otherwise [check here](https://github.com/nvm-sh/nvm) for the installation.
+
+```bash
+function change_node_version {
+	nvmrc="./.nvmrc"
+	if [ -f "$nvmrc" ]; then
+		version="$(cat "$nvmrc")"
+		nvm use $version
+	fi
+}
+
+chpwd_functions=(change_node_version)
+```
+
+The last step is to source your zshrc profile and voila 
+
+```bash
+source ~/.zshrc 
+```
+
+---
+
+This solution works for my needs and my terminal is faster again 🚀, feel free to suggest improvements. Until next time, stay curious !
