In the past few months we have been getting this question a lot: What do I use for managing dynamic data for my Decentralized App? We have for storing static data, but what about the data that keeps changing? InterPlanetary File System There are a number of exiting distributed databases like , , , , etc. GUN OrbitDB Scuttlebutt Textile Threads Although these existing databases are great, but we wanted a distributed database that will feel familiar, when you are coming from Web 2.0 & still has all the features that you would expect from a distributed database. Something like a distributed . MongoDB Enter AvionDB is a distributed database built on top of & . AvionDB OrbitDB IPFS When started our work on AvionDB, we had a few design goals in our mind. we Design Goals MongoDB/Mongoose like interface. Familiar developer interface: Your app can work locally without internet. For example, you can take notes on your notepad without (or even sync with other devices) connecting to the Internet. Local-first: All the data, whether it is on your device or on out in the network, it should be encrypted by default. Privacy-first: The database can be used natively on Mobile, Web & Desktop platforms. Cross-platform: How it Works? AvionDB uses OrbitDB stores to model MongoDB-like Databases. Each AvionDB instance can have several .Each Database can have several .Each Collection can have several . Databases Collections Documents The Javascript implementation works both in and with support for Linux, OS X, and Windows . The minimum required version of Node.js is now 8.6.0 due to the usage of ... spread syntax. LTS versions (even numbered versions 8, 10, etc) are preferred.
