1. About

This is a webapp designed to support the Cello v2 genetic circuit design software. In the future this webapp will run on cellocad.org, meaning installation will be unnecessary for most users.

2. Installation

Options

If you wish to create your own instance of the webapp, you have a few options.

1. Get the Docker image from Docker hub and run it.
2. Install the runtime dependencies, download a JAR file from the releases page of this repository, run the JAR file.
3. Install the developer dependencies, clone the contents of this repository, and build the webapp from source.

Each of these procedures is described below.

(Option 1) Docker

Download and install Docker.

• Linux: check your package manager / distribution instructions.
• Mac: Instructions
• Windows: Instructions (Windows 10) / Instructions (Windows 7/8)

Pull and run the image:

docker run --rm -p 8080:8080 -v /local/path/to/db:/data/db -v /local/path/to/users:/root/users -v /local/path/to/resources:/root/resources -t cidarlab/cello-webapp

Note the two /local/path/to directories. You will need to replace these with folders on your machine of your choosing. You can omit these -v clauses, but then the user database and projects storage will be destroyed when you stop the container.

Navigate to http://localhost:8080 to use.

(Option 2) Prepackaged JAR file

Runtime dependencies

• Java JRE 8 (Oracle, OpenJDK)
• MongoDB
• Yosys
  • Linux: check your package manager
  • Mac OSX: brew install yosys
  • Windows:
    • Download yosys-win32-mxebin-0.8.zip here: http://www.clifford.at/yosys/download.html
    • Unzip anywhere, add the folder containing yosys.exe to %Path%
• Graphviz
  • Linux: check your package manager
  • Mac OSX: brew install graphviz
  • Windows:
    • Download and install the latest msi, e.g. graphviz-2.38.msi, here: https://graphviz.gitlab.io/_pages/Download/Download_windows.html
    • Add the folder containing dot.exe, e.g. C:\Program Files (x86)\Graphvix2.38\bin, to %Path%
• The latest JAR from the releases page of this repository. Note that the Cello v2 CAD tool itself is bundled with the JAR you download.

Usage

Ensure that MongoDB is running, and then run the JAR file with:

java -jar <file>

(Option 3) Building from source

Developer dependencies

• Java JDK 8 (Oracle, OpenJDK)
• Maven
• MongoDB
• Yosys (see above)
• Graphviz (see above)
• Cello v2

Usage

Clone the repository.

git clone --recurse-submodules https://github.com/CIDARLAB/Cello-v2-webapp.git

Build.

cd Cello-v2-webapp/cello-webapp
mvn clean install

Run.

mvn spring-boot:run

3. Development

Code style

This project uses the Maven Checkstyle Plugin with a slightly relaxed version of google_checks.xml to enforce code style. If the code does not match the style requirements, maven will fail during the validate phase. If using Eclipse, you can use the Eclipse Checkstyle Plugin to show warnings when code does not meet the style requirements. You can also automatically format written code with the google-java-format, which can be used from the command line, or as a plugin in Eclipse or JetBrains IDEs.

Deployment

Docker Hub

• Docker images are built and deployed automatically via Travis CI. See .travis.yml.

• Manual:

  mvn docker:build
  mvn docker:push
  

Debug a running webapp in Eclipse

Navigate to Application.java in Eclipse, right-click on the main method, choose Debug As > Java Application.

Troubleshooting

If you want to clear or edit the database when running from Docker, invoke docker with the -i switch. Then enter the running container: docker exec -it [container-id] bash. You can find the container id from docker ps. Now invoke the mongo shell with mongo, and manipulate the database by hand.
