-# Flask-MongoDB Example Web App
-
-A simple example of a web app using [pymongo](https://pymongo.readthedocs.io/en/stable/index.html) to interact with a MongoDB database.
-
-It is possible to run this app remotely or locally. Instructions are included for each.
-
-## Run locally
-
-To run this app locally, first clone this repository to your local machine...
-
-`git clone url-to-this-repository`
-
-... and then do the following:
-
-### Set up a Python virtual environment
-
-This command creates a new virtual environment with the name `.venv`:
-
-```bash
-python3 -m venv .venv
-```
-
-#### Activate the virtual environment
-
-To activate the virtual environment named `.venv`...
-
-On Mac:
-
-```bash
-source .venv/bin/activate
-```
-
-On Windows:
-
-```bash
-.venv\Scripts\activate.bat
-```
-
-#### Install the dependencies into the virtual environment
-
-The file named, `requirements.txt` contains a list of dependencies - other Python modules that this app depends upon to run.
-
-To install the dependencies into the currently-active virtual environment, use `pip`, the default Python "package manager" - software that takes care of installing the correct version of any module into your in the correct place for the current environment.
-
-```bash
-pip3 install -r requirements.txt
-```
-
-### Set up a local MongoDB database server
-
-If running this app locally, you will not be able to connect to the NYU CS Department's MongoDB server. So you must have your app connect to either a cloud hosted database server, such as [MongoDB Atlas](https://www.mongodb.com/cloud/atlas), or download [MongoDB Community Server](https://www.mongodb.com/try/download/community) and run a local database server on your own machine.
-
-### Run the app
-
-1. define two environment variables from the command line: on Mac, use the commands: `export FLASK_APP=app.py` and `export FLASK_ENV=development`; on Windows, use `set FLASK_APP=app.py` and `set FLASK_ENV=development`.
-1. copy the file named `env.example` into a new file named `.env`, and enter your own MongoDB database connection credentials into that file where indicated.
-1. start flask with `flask run` - this will output an address at which the app is running locally, e.g. https://127.0.0.1:5000. Visit that address in a web browser.
-1. in some cases, the command `flask` will not be found when attempting `flask run`... you can alternatively launch it with `python3 -m flask run --host=0.0.0.0 --port=10000`.
-
-## Host on a web server
-
-The following steps outline how to host this application on NYU's **i6**.cims.nyu.edu web server. Other servers may vary.
-
-1. Familiarize yourself with web hosting steps on a CIMS server from the link: https://cims.nyu.edu/webapps/content/systems/userservices/webhosting.
-1. remotely log into the server using `ssh`.
-1. navigate into your web server account's `public_html` directory using `cd public_html`.
-1. clone this repository with `git clone url-to-this-repository`.
-1. navigate into the directory that was created by the clone operation.
-1. copy the file named `env.example` into a new file named `.env` (using `cp env.example .env`).
-1. edit the `.env` file using `emacs .env`, and enter your own MongoDB database connection credentials into that file where indicated. Save the changes within emacs by typing `Control-x` then `Control-s`. Exit emacs by typing, `Control-x` then `Control-c`.
-1. Make the files named `flask.cgi` executable by all with the command, `chmod a+x flask.cgi`.
-1. Your app should now be live on the web at https://i6.cims.nyu.edu/~$USER/$flask-app-directory/flask.cgi, where `$USER` is replaced with your own **i6** username and `$flask-app-directory` is replaced with the name of the sub-directory within `public_html` where your flask app code resides. Visit that address in your preferred web browser.
-
-## Continuous deployment
-
-While not required, it is possible to automatically update a copy of this web app anytime new changes to the code are pushed to GitHub. Such an automatic update of a deployed web app is known as "continuous deployment".
-
-Each repository on GitHub has a set of Settings for Webhooks. In those settings, it is possible to enter a "Payload URL" - GitHub will automatically issue an HTTP POST request to any URL you place there. The example web app code has a route designed to accept a webhook request from GitHub. That route automatically perform a `git pull` operation on the app's source code repository to update the code each time such a webhook request occurs.
-
-![Webhook settings](./images/webhook_settings.png)
-
-If attempting to test this webhook technique on a local instance of the web app, GitHub will not be able to make requests to your local machine. To solve this, is possible to use a tool such as [ngrok](https://ngrok.com/) to provide a public URL that forwards requests to your local machine. In such a scenario, with ngrok installed, you would set up ngrok to forward all HTTP requests to port `5000` of your local machine with the command, `ngrok http 5000`. Then enter the appropriate public ngrok address - something like `https://7ccd453a429f.ngrok.io/webhook/` - into the GitHub webhook "Payload URL" setting.
