gRPC

Self-hosted only

caution

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

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: ToolJet 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 the following to the volumes sections for plugins and server

./protos:/app/protos

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
  • 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.
