Open Event Website Generator

Open Event webapp

Build Status Heroku Dependencies Codacy Badge Maintainability codecov Reviewed by Hound Gitter Mailing Twitter Follow

The Open Event Website Generator 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).


Please join our mailing list to discuss questions regarding the project :!forum/open-event

Our chat channel is on gitter here:

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 pages on

2. Web App Generator

Components and Technology

Technologies used

The website 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. - 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_v1.js - Groups data of sessions, speakers, tracks etc from JSONs of v1
  • fold_v2.js - Groups data of sessions, speakers, tracks etc from JSONs of v2
  • 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
  • CoC.hbs : CoC.html - Code of Conduct for an event

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
  • generatorPage.js - Contains methods for testing of the generator form
  • roomPage.js - Contains methods for testing of the rooms page of the event
  • schedulePage.js - Contains methods for testing of the schedule page of the event
  • sessionPage.js - Contains methods for testing of the session pages of the event
  • speakerPage.js - Contains methods for testing of the speakers page of the event

Other Related Repositories

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.


Chat Channel:

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.


Chat Channel:

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).

Contains thumbnail images of sample events and main index.html file required for the showcase site

Accessing the Generator Web Form

Generator Screencast

  • Add your email id, select theme, select API version, select session style (single page for each session or expandable sessions), select data source

  • Then upload the zip file that contains all JSON files for speakers, sessions, sponsors, event, tracks and locations (These you should get from the 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.

Accessing the Generator via REST API

Please report issues here

Issue and Branch Policy

Before making a pull request, please file an issue. So, other developers have the chance to give feedback or discuss details. Match every pull request with an issue please and add the issue number in description e.g. like "Fixes #123".

We have the following branches :-

  • development All development goes on in this branch. If you're making a contribution, you are supposed to make a pull request to development. PRs to master must pass a build check and a unit-test (test/serverTest.js) check on Travis
  • master This contains shipped code. After significant features/bugfixes are accumulated on development, we make a version update, and make a release.

Contributions Best Practices


  • Write clear, meaningful git commit messages (Do read
  • 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 )
  • 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 )
  • 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.
