### 1. Install Homebrew

Install [Homebrew](https://brew.sh), a package manager for OSX:
```shell
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

This command changes occasionally. You can find the most recent command at [Homebrew](https://brew.sh)

- [npm](https://www.npmjs.com/) 6.4.1 or greater

#### 2.1. `n` For Node Version Management
#### 2.1. `pyenv` For Python version management
[pyenv](https://github.com/pyenv/pyenv) is a program to manage and swap between different versions of Python. To install:
```shell
brew install pyenv
```
And then follow the further installation instructions in https://github.com/pyenv/pyenv#installation to configure it.
#### 2.2. `n` For Node version management
[NPM](npmjs.org) is Node's package management tool. `n` is a tool for managing
different versions of Node. The following installs `n` and uses the long term support (LTS)
version of Node.
```shell
npm install -g n
n lts
npm install -g n
n lts
```
#### 2.2. `nvm` For Node Version Management
NVM is also a popular tool for node verison managmement. Install it with Homebrew (instructions can be found with a simple Google search), and make sure you have a Node version installed higher than 10.15.3, and use it. I have arbitrarily chosen version `12.16.2` for this example.
### 3. Install NPM dependencies
```shell
nvm use 12.16.2
npm install
npm rebuild node-sass
```
### 3. Install NPM Dependencies
### 4. Install and use `virtualenvwrapper` (optional)
We suggest using a virtualenv to separate the python dependencies for this project from python dependencies for other projects.
Install [virtualenvwrapper](https://virtualenvwrapper.readthedocs.io/en/latest/install.html):
```shell
npm install
npm rebuild node-sass
pip install virtualenvwrapper
```
### 4. Install `virtualenvwrapper`
Then follow the [virtualenvwrapper installation instructions](https://virtualenvwrapper.readthedocs.io/en/latest/install.html) docs to configure virtualenvwrapper for your terminal.
You'll need the `pip` package [virtualenvwrapper](https://virtualenvwrapper.readthedocs.io/en/latest/install.html) installed. Installation is pretty easy; run this command for the 3.6.x version of Python you're using for this project:
Set up your virtualenv:
```shell
pip install virtualenvwrapper
mkvirtualenv notifications-admin
```
...However, you'll need to configure it to run in your `bash` terminal. Add the following lines to your `~/.bash_profile` **if** you're using `pyenv` to manage your python versions:
*Note: Python version 3.6.3 is the 3.6.x version arbitrarily chosen for this example.*
```bash
export WORKON_HOME=~/virtualenvs
export VIRTUALENVWRAPPER_HOOK_DIR=$WORKON_HOME/hooks
source ~/.pyenv/versions/3.6.3/bin/virtualenvwrapper.sh
```
If no `~/virtualenvs` directory exists, make one.
If you're using the main system Python version on an OSX machine, your final `~/.bash_profile` line will look more like this:
```bash
source /usr/local/bin/virtualenvwrapper.sh
```
Please see the [virtualenvwrapper](https://virtualenvwrapper.readthedocs.io/en/latest/index.html) website for more installation and configuration info. This step gives you access to `mkvirtualenv` on the command line.
### 5. Setup Virtual Environment
The app runs within a virtual environment. We use `mkvirtualenv` for easier working with `venvs`
**Using Your Machine's System Python:**
```shell
mkvirtualenv -p /usr/local/bin/python3 notifications-admin
```
**Using pyenv:**
*Note: Python version 3.6.3 is the 3.6.x version arbitrarily chosen for this example.*
If you need to specify a certain version of python you can do this using `-p`, for example:
```shell
mkvirtualenv -p ~/.pyenv/versions/3.6.3/bin/python notifications-admin
```
### 6. Install Python Dependencies
Activate your virtualenv:
```shell
workon notifications-admin
```
### 5. Install Python dependencies
Install dependencies and build the frontend assets:
```shell
workon notifications-admin
./scripts/bootstrap.sh
./scripts/bootstrap.sh
```
**Note:** You may need versions of both Python 3 and Python 2 accessible to build the python dependencies. `pyenv` is great for that, and making both Python versions accessible can be done like so:
```shell
pyenv global 3.6.3 2.7.15
pyenv global 3.6.3 2.7.15
```
### 7. Rebuilding the frontend assets
If you want the front end assets to re-compile on changes, leave this running
in a separate terminal from the app

npm run watch
