![]() More about the stack is available in humans.txt. The app is fully integrated with the PouchDB changes feed for instant updates. The paid version syncs data with CouchDB 2 for data persistence and sharing across devices. Financierįinancier is a freemium personal budgeting app that uses PouchDB to store your budget data. The combination of CouchDB and PouchDB enabled these apps to work consistently despite the extreme network unreliability of sub-saharan Africa. To tackle the Ebola outbreak, they built mobile apps and dashboards to help track the spread of infection in the field. ![]() eHealth AfricaĮHealth Africa is an American-Nigerian NGO specialising in the development and deployment of tech for health. View split diffs in the browser with syntax highlighting, or in the command-line using the -cli flag. Deltaĭelta is a command-line utility for text diffs. Under the hood, it leverages CouchDB and PouchDB. It syncs contacts, calendars, and files between your personal devices and server. Cozy CloudĬozy is a personal cloud that you can host, customize, and fully control. ![]() CloudwallĬloudwall is an operating system for noBackend webapps, based on CouchDB and PouchDB. See a video of it in action or read about it on Mozilla Hacks. BikeCommuteīikeCommute is a FirefoxOS app that registers an NFC tag to track bike commuters in the Mozilla Portland office. Its backed is powered by CouchDB and it uses PouchDB on the web client, desktop client and mobile native app for offline access, live sync, revisions and much more. It runs on Windows, Linux, macOS, Android, iOS & web. Newt lets you read, listen and write thousands of books across devices natively. The main module uses URL-friendly symbols ( A-Za-z0-9_-) and returns an ID with 21 characters (to have a collision probability similar to UUID v4).A list of known products and services that are using PouchDB. nanoid-good to be sure that your ID doesn't contain any obscene words.nanoid-dictionary with popular alphabets to use with nanoid/generate.ID size calculator to choice smaller ID size depends on your case.Nano ID uses a better algorithm and is tested for uniformity. The spread will not be even there will be a lower chance for some symbols to appear compared to others-so it will reduce the number of tries when brute-forcing. Random % alphabet is a popular mistake to make when coding an ID generator. These modules use unpredictable hardware random generator. Instead of using the unsafe Math.random(), Nano ID uses the crypto module in Node.js and the Web Crypto API in browsers.

Nano ID is quite comparable to UUID v4 (random-based). The generator supports Node.js, React Native, and all browsers. ![]()
