gRPC
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.
