All the 9 | credit for the magic goes to ElectricSQL! 10 | 11 | ![A four-way sync between browsers](fourway.png) 12 | 13 | ## Instructions 14 | 15 | 1. Make a copy of this template into a new directory: 16 | 17 | ```sh 18 | npx tiged tinyplex/tinybase-ts-react-electricsql my-tinybase-app 19 | ``` 20 | 21 | 2. Go into the directory: 22 | 23 | ```sh 24 | cd my-tinybase-app 25 | ``` 26 | 27 | 3. Install the dependencies: 28 | 29 | ```sh 30 | npm install 31 | ``` 32 | 33 | Note that you will also need to install [Docker](https://docs.docker.com/engine/install/). 34 | 35 | 4. Start Postgres and Electric using Docker: 36 | 37 | ```sh 38 | npm run backend:up 39 | ``` 40 | 41 | 5. Setup the database schema: 42 | 43 | ```sh 44 | npm run db:migrate 45 | ``` 46 | 47 | 6. Generate the type-safe client: 48 | 49 | ```sh 50 | npm run client:generate 51 | ``` 52 | 53 | 7. Run the server: 54 | 55 | ```sh 56 | npm run dev 57 | ``` 58 | 59 | 8.
