• Ecom is a django single page (SPA) web app running on apache as a web server.
• Apache proxies requests to the WSGI application which invokes the python application itself.
• The latest multiprocessing apache module is used to create parallel replicas of our app. Each apache "event_worker" is 1 process and 1 python app. 1 process launches multiple threads so that each app is concurrently accessed by multiple users. The big performance advantage of the "event_worker" over the regular worker is that once the connection is idle, the thread gives back the control of the socket to Apache.
• There is a full decoupling of the front end with React written in JSX which is then tranpiled to vanilla javascript through the dev and build scripts specified in the package.json file.
• React components live in the "ecom/frontend" django app. Redux is extensively used to manage state in order to guarantee a single source of truth and avoid having the multiple components managing state. Each component gets the state as props from the store.
• The continuous delivery pipeline is triggered by a git push to origin by any member that has write access to this repo.
• The git push triggers a webhook where both github and jenkins are listening on in order to build the jenkins pipeline.
• Specifications of the Jenkinsfile can be found above.
• Any push to origin will trigger both webhooks however jenkins will only build the source code located in the "master" branch.
