audio-sharing

Simple Python Django + HTML + vanilla JS application for recording and sharing audio

• This project is configured to be deployed on Heroku: https://www.heroku.com/
• Audio recording is done by using https://github.com/higuma/web-audio-recorder-js

File Upload

• First choice was to upload to DropBox using django-storages: https://github.com/jschneier/django-storages
• Because heroku has a 30s time limit for each request, I tried using django-queued-storage (https://github.com/jazzband/django-queued-storage) to first store the file in local file system (not working well with heroku's file system) or database (still too slow) and then upload it in a background worker using celery => still can't beat 30s for large files :(
• Settled with using django-s3direct (https://github.com/bradleyg/django-s3direct) to upload files directly from client to Amazon S3

Some environment variables we should pay attention to

• SECRET_KEY: make sure it's different between development and production
• DJANGO_SETTINGS_MODULE: for this project, it should be commons.settings.dev for development and commons.settings.prod for production
• ALLOWED_HOSTS: Read Django's Doc: https://docs.djangoproject.com/en/dev/ref/settings/#allowed-hosts
