# Kinto
# «A lightweight JSON storage service with synchronisation and sharing abilities.»
# It's a FOXING DATABASE!
# For the Web.
# That syncs.
# With permissions.
# We all build JavaScript applications.
# Sometimes, these applications need to store data.
## A new idea?
- Design the API (URL and protocol)
- Implement the server parts
- Deploy, scale, etc.
- Consume the API on the client.
------
Aren't you tired of doing the same things over and over again?
## With Kinto
1. Deploy an instance (ops are happy to do it, they know it!)
2. Integrate with one of the existing clients (Kinto.js, Kinto.py)
3. ???
4. Profit !
## Use cases
- Addons blocklists (Graphic cards drivers, Addons, etc.)
- OneCRL — SSL Certificate Revocation Lists
- Fennec OTA (Hyphenation and fonts)
- Whatever you want to sync in Firefox!
## Offline first
## Features
- Synchronisation
- Permissions
- Push notifications
- Ops friendly
## Ecosystem
- Kinto.js (landed in firefox!), kinto.py
- Encrypt if you need (WebCrypto)
- Data signing (*)
- File storage (*)
## Capitalize
-----
- Do not reinvent everything each time
- Respect HTTP best practices
- Ease the job for Ops
- Keep the good ideas of Firefox Sync.
## Other solutions
- Parse / Firebase, but open source
- Remote Storage
- CouchDB / PouchDB
- Sync
## Put back the user in control.
-----
- Optional validation of the data schema
- Encryption made easy (webcrypto + kinto.js)
- Permissions → mutualise the deployment
