This is a web-based version of Robert and Jonas Gifford's "FISH", a fish banks simulator for environmental psychology studies.

More information on the original FISH here: http://web.uvic.ca/~rgifford/fish/

Requirements

Please ensure these requirements are installed before proceeding to the Installation section.

• Node (and npm)
• Mongodb
• Ruby
• Sass (through gem install sass)

Installation

1. Navigate to the fish directory in a terminal window
2. Run the command npm install (install dependencies specified in the package.json file)

• Note: You may need escalated privileges to run and will get an error. If so, use the command sudo npm install instead.
• NOTE: This will run a script post install as well. See: Usage.

3. Run the command npm start (on Windows or OSX) or nodejs app.js on Linux to start the server.
4. Navigate to localhost:8080

Usage

Scripts for Developers

These are located in the developer_scripts folder

• npm run populatedb Run post-install.
• This populates the database with a user "Admin" and a password "123456789"
• npm run cleandb This will clean all the collections defined in the file (experimenters, microworlds, and sessions)
• npm run resetdb runs cleandb then populatedb
• npm run devreset runs cleandb then populate db and then starts up the server.
• npm run sass watches for style changes

Docker

This project is also dockerized (no official repository available however). This project uses and tested on the following Docker technologies:

• Docker for Mac:
  • Client version: 17.03.1-ce
  • Server version: 17.03.1-ce
• Docker Compose version 3

Container

The node application is run in a container named fish and the MongoDB is run in a container named mongo-fish. See docker-compose.yml for more details.

Volumes

The following volumes are bound from host to the Docker container

1. The whole directory of this repository is mounted on fish to /fish/app
2. mongo.log is mounted on mongo-fish to /logs/mongo.log

You can see more details on Docer setup

Docker Setup

The following is a diagram of the Docker setup:

From the above diagram you can infer several things:

1. You can access the Fish application from http://localhost:8080 from your browser
2. Since all Fish files in this repo is mounted on the Fish container, any changes on the repo will be reflected onto the Fish container. Therefore if you make changes to the application you don't need to re-build the containers. See Building the images for more info
3. Since the /logs/mongo.log is mounted to mongo.log, you may see all the mongo logs being saved to mongo.log so you can check it out in the future

Building the images

Before trying to run Dockerized application, please run npm run build-docker first beforehand. This command only needs to be run once, unless you want to rebuild the containers due to changes. Several possible changes that needs rebuilding:

1. Changing the commands that the containers execute
2. Changing the base image of the containers
3. Adding things to the containers' Dockerfiles, either Dockerfile-app or Dockerfile-Db
4. Other things that modifies the Dockerfiles

Usage

In order to use the Dockerized version do the following

1. npm run build-docker
2. Run the Docker services, one of
   • npm run start-docker (standard mode)
   • npm run start-daemon-docker (daemon mode a.k.a Docker detached mode)
3. After running one of the above you should run npm run docker-populatedb. It's the populate DB setup but for the docker setup

If you run in daemon mode then you can do npm run stop-daemon-docker to stop daemon mode

Logs

If Docker was run in non-detached mode then logs will be visible on console stdout. The node application and MongoDB logs may also be found in fish.log and mongo.log respectively.

If Docker was run in detached mode you may see logs by running the following commands:

• node application: npm run logs-docker-fish
• MongoDB: npm run logs-docker-mongo-fish

Administrator

1. Navigate to http://localhost:8080/admin

2. Log in with the following credentials:

   • Username: Admin
   • Password: 123456789

3. You now have access to the microworlds

4. Create and activate a microworld if you wish to run an experiment with users Note: Look at the Code for the experiment on an active microworld. eg Active Microworld: QQ5HQP

Users (identified by an arbitrary ID#, which is not pre-assigned. Any number will work.)

1. Navigate to http://localhost:8080/
2. Enter the Experiment number of an active microworld
3. Enter an ID number
4. Fish!
