Render

Render is a cloud infrastructure and web hosting platform.

Electric and Render

You can use Render to deploy an Electric sync service and your client application.

[!Info] Postgres on Render and logical replication Render does provide managed Postgres hosting. However, this doesn't yet support logical replication, so you can't currently use Electric with it.

If you need Postgres hosting to use with Render, Neon and Supabase both work great.

[!Tip] Need context? See the Deployment guide for more details.

Deploy Electric

Deploy Electric as a Web Service using their deploy from a container registry option.

In the Render dashboard, create a new Web Service, select Existing Image and paste electricsql/electric as the image URL. Then on the next screen set a DATABASE_URL and any other config as environment variables.

You can also optionally enter /v1/health as the path for a health check.

Under "Advanced" make sure you add a Persistent Disk and set the Mount path to e.g.: /var/electric. Then also set the ELECTRIC_STORAGE_DIR environment variable to the same mount path, e.g.: ELECTRIC_STORAGE_DIR=/var/electric.

Deploy your app

You can deploy your app on Render as a Static Site. For example, you can deploy our standalone-basic-example by:

selecting "Public GitHub Repository" and pasting https://github.com/electric-sql/standalone-basic-example as the value
setting the publish directory to dist
setting a VITE_ELECTRIC_URL environment variable to the URL of your Electric web service, such as https://YOUR_WEB_SERVICE_NAME.onrender.com

Then make sure that your Postgres database has an items table with an id column and insert some data into it.

Example

Render supports Blueprints to deploy infrastructure as code. The following example shows how to deploy Electric and an example web app that connects to it.

[!Warning] Requires an existing Postgres running somewhere else The Blueprint above requires a DATABASE_URL to an existing Postgres database hosted somewhere else.

Also, as per the example above, the example app it deploys assumes you have an items table in your database.

`render.yaml` Blueprint

Clone github.com/electric-sql/render-blueprint or copy the following config into a render.yaml file:

yaml

services:
  - type: web
    runtime: image
    name: electric
    image:
      url: electricsql/electric:latest
    disk:
      name: storage
      mountPath: /var/electric
      sizeGB: 20
    envVars:
      - key: DATABASE_URL
        sync: false
      - key: ELECTRIC_STORAGE_DIR
        value: '/var/electric'
  - type: web
    runtime: static
    name: app
    buildCommand: VITE_ELECTRIC_URL="https://${ELECTRIC_HOST}.onrender.com" npm run build
    staticPublishPath: ./dist
    envVars:
      - key: ELECTRIC_HOST
        fromService:
          name: electric
          type: web
          property: host

You can then follow the instructions here to deploy the Blueprint on Render.

In short, you push the render.yaml to a repo, open the Render Dashboard, click "New > Blueprint", connect the repo and enter your DATABASE_URL when prompted.
