    The fullstack database.

    Triplit is an open-source database that syncs data between server and browser in real-time.

    npm create triplit-app@latest

    Live updating queries

    Triplit's queries are reactive by default, so you can build apps that update in real-time without any extra work.
    Automatic caching and syncing on the client
    Full relational support for querying connected data
    Typescript support for all data returned from queries
    React Hooks to subscribe to queries in your UI

    use-messages.ts
    import { useQuery } from "@triplit/react"
    import { client } from "@/lib/triplit"
    
    export function useMessages(convoId: string) {
      const deliveredMessagesQuery = client
        .query("messages")
        .where("conversationId", "=", convoId)
        .order("created_at", "DESC")
        .syncStatus("confirmed")
    
      const {
        results: messages,
        fetchingRemote,
        fetching,
        error,
      } = useQuery(client, deliveredMessagesQuery)
    }
    Triplit would be [...] your MongoDB or MySQL, but it’s also your Drizzle, your schema definition and query language. But then it’s also your Tanstack query which you use on the client side. It’s everything.

    After a thorough evaluation of similar tools, we decided on Triplit as a key technology in a technically demanding client project and haven’t looked back since! Triplit has allowed us to move faster than ever when it comes to reliably syncing data between many users while keeping every interaction fast, even when users don’t have good connections. We are looking forward to using it in future projects.

    schema.ts
    import { Schema as S } from "@triplit/db";
      
    export const schema = {
      todos: {
        schema: S.Schema({
          completed: S.Boolean(),
          created_at: S.String({ 
            default: S.Default.now()
          }),
          id: S.String({ 
            nullable: false, 
            default: S.Default.uuid()
          }),
          listId: S.String({ nullable: true }),
          text: S.String(),
        }),
      },
    };
    I've been using Triplit on my React native app for a while and it works great. Highly recommend. It's the only local-first database that hits these points for me: 1) Good and sane query language (not SQL). 2) Great typescript support. 3) Offline support. The cherry on top is that it's open-source and self-hostable.
