gRPC

:::caution only self-hosted deployments will have access to a gRPC datasource that is capable of handling unary requests and responses. :::

• Setup
• Querying gRPC

Setup

Step 1: Upgrade ToolJet to the version 2.5 or above

Find instructions on how to do this in the setup guides located here: https://docs.tooljet.com/docs/setup/.

Step 2: Add proto files

At the root, create a directory named "protos" and add a "service.proto" file inside it.

Step 3: Mount Volumes

In the docker-compose.yml add

./protos:/app/protos

to the 2 volume sections for plugins and server

Step 4: Reboot the instance

docker-compose up -d

Querying gRPC

After setting up your proto files, you should be able to establish a connection to gRPC by going to the global datasource page.

Connect the gRPC datasource

ToolJet requires the following to connect to gRPC servers:

• Server URL
• Authentication type (None, Basic, Bearer, and API key)

Once you have added the gRPC from the global datasource page, you'll find it on the query panel of the application.

Creating query

You can now query a particular RPC method of the added services.
