What is Electric Next?

This is a clean rebuild of the ElectricSQL sync engine. One that's informed by the lessons learned building the previous system. See James' blog post for background on the change: https://next.electric-sql.com/about

It provides an HTTP API for syncing Shapes of data from Postgres. This can be used directly or via client libraries and connectors.

It's also simple to write your own client in any language.

Getting Started

See the Quickstart guide to get up and running. In short, you need to:

1. have a Postgres database with logical replication enabled; and then to
2. run Electric in front of it, connected via DATABASE_URL

For example, using Docker Compose from the root of this repo:

docker compose -f .support/docker-compose.yml up

You can then use the HTTP API to sync data from your Postgres. For example, to start syncing the whole foo table:

curl -i 'http://localhost:3000/v1/shape/foo?offset=-1'

Or use one of the clients or connectors, such as the useShape React hook:

import { useShape } from '@electric-sql/react'

function Component() {
  const { data } = useShape({
    url: `http://localhost:3000/v1/shape/foo`,
    where: `title LIKE 'foo%'`,
  })

  return JSON.stringify(data)
}

Again, see the Quickstart and the Docs for more details.

HTTP API Docs

The HTTP API is defined in an OpenAPI spec in docs/electric-api.yaml.

Developing Electric

We're using asdf to install Elixir, Erlang, and Node.js. Versions are defined in .tool-versions.

Mac setup

brew install asdf
asdf plugin-add nodejs elixir erlang
asdf install

You'll probably need to fiddle with your bash/zsh/etc rc file to load the right tool into your environment.
