Full-Stack React/Node Application Installation

1. Clone this repo to your local drive.

   details

   1. Start a terminal app, such as Ubuntu for Windows Subsystem for Linux
   2. Create a src directory in the user's home directory and go in it

      cd && mkdir src && cd src
      

   3. Clone the repository

      git clone https://github.com/hackforla/jobs-for-hope
      

2. Change to the jobs-for-hope directory:

   cd jobs-for-hope
   

3. Install the node server npm depedencies:

   npm install
   

4. Obtain the .env file from the slack channel and place it in this directory. It contains private info (i.e., the production database connection string) that we cannot put in this public GitHub repo.

5. Change to the client directory:

   cd client
   

6. Install the client (React) dependencies:

   npm install
   

To Run the React/Node Application

1. Run npm start from the jobs-for-hope directory to start the node server.
2. Run npm start from the jobs-for-hope/client directory to start the react app and open the browser.

Backend Python Scraper Setup

1. Virtualenv (optional, but will be useful if you eventually want to have multiple python projects)

   show

   1. Set up virtualenv

      1. Install virtualenv using pip

         pip install virtualenv virtualenvwrapper
         

      2. cd into project directory

         cd jobs-for-hope/backend
         

      3. create the virtualenv

         virtualenv venv
         

         Alternative for systems where python 2.7 is not the default

         1. Specify the python location when creating the virtualenv

            virtualenv -p /usr/local/bin/path/to/python2.7 venv # use this if the system default is python3
            

      alternative setup using virtualenvwrapper

      1. Install virtualenv using pip

         pip install virtualenv virtualenvwrapper
         

      2. Create directory to hold virtual environments

         mkdir $HOME/.virtualenvs
         

      3. Find out where virtualenvwrapper.sh is located for next step

         which virtualenvwrapper.sh
         

      4. Make .bash_profile call .bashrc (reference:http://www.joshstaiger.org/archives/2005/07/bash_profile_vs.html)

         1. Add this to .bash_profile

            if [ -f ~/.bashrc ]; then
              source ~/.bashrc
            fi
            

      5. Add to .bashrc

         export WORKON_HOME=$HOME/.virtualenvs
         export PATH="/path/to/virtualenvwrapper:$PATH"
         source virtualenvwrapper.sh
         

      6. Start a new terminal session or call .bashrc

         source ~/.bashrc        # activate virtualenvwrapper.sh, just for the first time
         

      7. Create the virtualenv

         mkvirtualenv jobs-for-hope
         

         Alternative for systems where python 2.7 is not the default

         1. Specify the python location when creating the virtualenv mkvirtualenv -p /usr/local/bin/path/to/python2.7 jobs-for-hope # use this if the system default is python3

   2. Activate the virtualenv

      source venv/bin/activate
      

      for virtualenvwrapper

      workon  // list the existing virtual environments, blank if none is created
      workon jobs-for-hope  // activate virtual environment, not needed when first creating the virtualenv
      

   3. Do work and run python within the virtualenv

   4. Deactivate the virtualenv

      deactivate // switch back to system python
      

   1. All python commands should be run inside the jobs-for-hope virtualenv if you choose to set it up. You will have to make sure the virtualenv is activated before following the steps.

2. Install project dependencies

   cd backend
   pip install -r ./requirements.txt
   

3. Setup for the scrapers

   1. Download the database.ini file from the slack channel into the backend directory
   2. Dump the aws database to a file (reference database.ini for values)

      pg_dump -d <database> -h <host> -U <user> -C -f jobsforhope.sql
      

   3. restore to the local database

      psql -h localhost -U postgres -d jobsforhope -f jobsforhope.sql
      

To run the scraper

1. Switch to the backend directory

   cd backend
   

2. To run all the scrapers

   python scraper_runner.py
   

3. To run a single scraper

   python scraper_runner.py scrapers/prototypes.py
   

Checking the database for scraped data

1. Use DBeaver
2. Add a postgres database connection with the .env file credentials from the slack channel.
3. The jobs are in the jobs table.
