Open Event Web App

The Open Event Web App project has TWO components :

An event website generator
The actual generated website output.

The web generator application can generate event websites by getting data from event JSON files and binary media files, that are stored in a compressed zip file. You can also access the application through a REST API. Websites that are generated by the "web app generator" can be uploaded to any web location, e.g. on Github pages or any server (e.g. via ftp).

1. Event Website Output

The component that is generated from the web app is the event website. Several sample event sites using the sample from the open-event repo were generated, showcased on the main index page and added to this repo as a Github Pages site. You can have a look at showcase page on http://fossasia.github.io/open-event-webapp/ We also have a custom domain at http://sched.eventyay.com to which the former link is redirected.

2. Web App Generator

Components and Technology

Technologies used

The webapp generator uses the following technologies :-

1. HTML/CSS/Javascript based frontend

2. SASS - SASS to write optimized CSS.

3. Node.js - Javascript for the generator backend

4. Express.js - Server framework

5. Handelbars - Template for rendering

6. Socket.io - For handling multi-user client, with progress of upload/generation

7. WebdriverJs - Official Javascript Implementation of Selenium for testing generated event websites

Components of the Generator

1. Webform

The source of the webform can be found here.

It consists of :-

index.html - The webform page
form.js - The script that uploads the zips, and starts the generator process

2. Generator

The generator runs on a ExpressJS server, using this main app script.

3. Scripts

generator.js - Does the main generation tasks, and controls other scripts
fold.js - Groups data of sessions, speakers, tracks etc from JSONs
dist.js - Creates folders, cleans folders, unzips/zips packages
ftpdeploy.js - Deploys finished website to organiser's server (optional)
mailer.js - Sends mail to organiser notifying of successful creation
buildlogger.js - Displays build logs while generating webapp
deploy.js - Automatically deploys generated event sites to user's github account
gulpfile.js - Creates minified js and css for generated webapp

4. Templates

The HTML pages of the generated website are created using Handelbars templates.

You can find all the templates here -

footer.hbs : Common template for footer on all pages
navbar.hbs : Common template for navbar on all pages
event.hbs : index.html - Home page
rooms.hbs : rooms.html - Venues page
schedule.hbs : tracks.html - Tracks page
speakers.hbs : speakers.html - Speakers page
session.hbs : session_id.html - Individual Session page having a particular id

5. Selenium

Contains scripts related to testing different pages of the generated website.

basePage.js - Contains methods common to all the pages of the event site
eventPage.js - Contains methods for testing of the index page of the event
trackPage.js - Contains methods for testing of the tracks page of the event

Open Event Format Definition

The Open Event Project enables the exchange of data between all components as well as with other services through a standardized Format. The Open Event repository provides a sample implementation of the format. It includes JSON files for all relevant event information and binary data for images and audio files.

Repository: https://github.com/fossasia/open-event

Chat Channel: https://gitter.im/fossasia/open-event

Open Event Server

The Open Event Server enables organizers to manage events from concerts to conferences and meetups. It offers features for events with several tracks and venues. Event managers can create invitation forms for speakers and build schedules in a Drag & Drop interface. The event information is stored in a database, which can be a sqlite-db file or saved in json itself. The system provides API endpoints to fetch the data, and to modify and update it. Organizers can import and export event data in a standard compressed file format that includes the event data in JSON and binary media files like images and audio.

Open Event Android App

The Open Event Android Project consists of two components. The App Generator is hosted web application, that is hosted on a server and generates an event Android app from a zip with JSON and binary files (examples here) or through an API. The second component we are developing in the project is generic Android app - the output of the app generator. The mobile app can be installed on any Android device for browsing information about the event. Updates can be made automatically through API endpoint connections from an online source (e.g. server), which needs to defined in the provided event zip with the JSON files. The Android app has a standard configuration file, that sets the details of the app (e.g. color scheme, logo of event, link to JSON app data).

Accessing the Generator Web Form

Once deployed, you'll find the generator running on http://localhost:5000, it should look like this

Add your email id, select session style (single page for each session or expandable sessions),
Then upload the zip file that contains all JSON files for speakers, sessions, sponsors, event, tracks and locations (These you should get from an orga-server or through the API after you have created your event there).
Now, when you click on GENERATE APP and DOWNLOAD button, you'll get to download a zip of the event website. You can also deploy the web site to your Github Pages by clicking on DEPLOY button.

This contains shipped code. After significant features/bugfixes are accumulated on development, we make a version update, and make a release.

Contributions Best Practices

Commits

Write clear, meaningful git commit messages (Do read http://chris.beams.io/posts/git-commit/)
Make sure your PR's description contains GitHub's special keyword references that automatically close the related issue when the PR is merged. (More info at https://github.com/blog/1506-closing-issues-via-pull-requests )
When you make minor changes to a PR (like for example fixing a failing Travis build or some small style corrections or minor changes requested by reviewers) make sure you squash your commits afterward. (Learn how to squash at https://davidwalsh.name/squash-commits-git )
When you're submitting a PR for a UI-related issue, it would be great if you add a screenshot of your change or a link to a deployment where it can be tested out along with your PR.

Feature Requests and Bug Reports

When you file a feature request or when you are submitting a bug report to the Issue tracker, make sure you add steps to reproduce it.

Join the development

Before you join development, please set up the project on your local machine, run it and go through the application completely. Press any button that you can see and see where it leads. Explore. (Don't worry, Nothing will happen to the app due to the exploring: wink: The only thing that will happen is, you'll be more familiar with what, is where and might even get some cool ideas on how to improve various aspects of the app.)
If you would like to work on an issue, drop in a comment on the issue.

Do read the Open Source Developer Guide and Best Practices at FOSSASIA.
