apps.loklak.org

Loklak is a server application which is able to collect messages from various sources, including Twitter. The server contains a search index and a peer-to-peer index sharing interface. All messages are stored in an elasticsearch index. An automatic deployment from the development branch at GitHub is available for testing here https://loklak-server-dev.herokuapp.com

'Lok Lak' is also a very tasty Cambodian stir-fry meat dish (usually beef) with a LOT of fresh black pepper. If you ever have the chance to eat Beef Lok Lak, please try it. I hope not to scare vegetarians with this name, currently I am one as well.

How to create a loklak app

1. Create your app

   • Make a subdirectory in fossasia/apps.loklak.org/[your-app] folder
   • Add at least three files into this folder, named index.html, app.json and screenshot.png. For an easy quick-start, use and copy the app boilerplate from https://github.com/fossasia/apps.loklak.org/tree/master/boilerplate
   • All libraries, css files, javascript and fonts must be either already existent in loklak or you must add this to your app path as well.
   • The screenshot must be cropped into 640 x 640 pixels and in .png format.
   • The file index.html is the landing page of your app. Use /js/angular.min.js from the loklak root path for your application. The app should make use of the json libraries in /js. If applicable, make use of the bootstrap style from /css.
   • The file app.json must be in json-ld format (see http://json-ld.org/) and must contain the SoftwareApplication object from schema.org: https://schema.org/SoftwareApplication -- just copy-paste an existing app.json from another app to start you own file
   • Modify the field "permissions" in app.json: it must contain a comma-separated list of all api paths, that the app calls. This is used to apply authorization markers to the app, so it becomes visible if the app is actually usable for the user. Examples: "permissions":"/api/suggest.json", or "permissions":"/api/settings.json,/api/account.json"
   • Alternatively, you can use loklakinit tool to automatically create your app directory structure, app.json and initial dummy HTML, CSS, JS and documentation files to quickly get you started with your development work. Learn more about the use of loklakinit tool [here](To know more in details about developing a Loklak app, preparing your app for store listing and updating Loklak app wall with your new app, please follow this tutorial.

2. Check quality of your app

   • Do a json-ld validation: use https://developers.google.com/structured-data/testing-tool/ to check your app.json
   • Call https://api.loklak.org/api/apps.json to see if your app.json is included in the app list
   • Check if all declarations in your app.json relate to your own app (if you copy-pasted another app.json, you may have forgotten to change some fields)
   • Under Application Category try and choose one of the following Categories: a. Accounts b. Game c. Visualizer d. Scraper e. Search f. Internet of Things
   • List an appropriate Application Sub Category too
   • Check the style and behaviour of your app: don't deliver half-done code.
   • Open your index.html in different browser to check that your code is not browser-specific
   • Add a backlink in your app to /apps/ to make it possible that users can browse from your app to all other apps

3. Publish your app

   • Send a pull request to https://github.com/fossasia/apps.loklak.org
   • All your files must be contained into one commit

How to run Loklak Apps locally

You need to have NodeJS and NPM. To run Loklak Apps locally, follow the next steps

1. Open apps.loklak.org project directory in terminal
2. Run npm install
3. Run npm start
4. This starts the development server at port 8080. Open browser and visit http://127.0.0.1:8080

How to run tests

Loklak apps site uses jasmine testing framework with protractor for testing. To run the tests follow the steps mentioned below.

1. Open the project directory in terminal.
2. Run npm install if you have not already
3. Run npm run update-driver
4. Run Loklak apps using npm start
5. Run npm run start-driver
6. Finally start tests using npm test

How users will discover your app

The loklak front-end will compute an aggregation of all those app.json descriptions and provide this in /api/apps.json as a list of the single app.json files. A front-end (another app) will provide an overview of the given apps in visual form. This will be linked in the loklak front-end.

Code practices

Please help us follow the best practice to make it easy for the reviewer as well as the contributor. We want to focus on the code quality more than on managing pull request ethics.

• Single commit per pull request
• Reference the issue numbers in the commit message. Follow the pattern Fixes #<issue number> <commit message>
• Follow uniform design practices. The design language must be consistent throughout the app.
• The pull request will not get merged until and unless the commits are squashed. In case there are multiple commits on the PR, the commit author needs to squash them and not the maintainers cherrypicking and merging squashes.
• If the PR is related to any front end change, please provide link to a sample deployment of the site with the changes you have made.
