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: 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
|
|
|
|
```bash
|
|
./protos:/app/protos
|
|
```
|
|
|
|
to the 2 volume sections for **plugins** and **server**

|
|
|
|
</div>
|
|
|
|
<div style={{textAlign: 'center'}}>
|
|
|
|
<img className="screenshot-full" src="/img/datasource-reference/grpc/proto2.png" alt="gRPC: datasource" width='500'/>
|
|
|
|
</div>
|
|
|
|
### Step 4: Reboot the instance
|
|
|
|
```bash
|
|
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](/docs/data-sources/overview) page.
|
|
|
|
### Connect the gRPC datasource
|
|
|
|
ToolJet requires the following to connect to gRPC servers:
|
|
|
|
- **Server URL**
|
|
- **Authentication type** (None, Basic, Bearer, and API key)
|
|
|
|
<div style={{textAlign: 'center'}}>
|
|
|
|
<img className="screenshot-full" src="/img/datasource-reference/grpc/connection.png" alt="gRPC: connection" />
|
|
|
|
</div>
|
|
|
|
Once you have added the gRPC from the global datasource page, you'll find it on the query panel of the application.
|
|
|
|
<div style={{textAlign: 'center'}}>
|
|
|
|
<img className="screenshot-full" src="/img/datasource-reference/grpc/grpcgds.png" alt="gRPC: connection" />
|
|
|
|
</div>
|
|
|
|
### Creating query
|
|
|
|
You can now query a particular RPC method of the added services.
|
|
|
|
<div style={{textAlign: 'center'}}>
|
|
|
|
<img className="screenshot-full" src="/img/datasource-reference/grpc/query.png" alt="gRPC: connection" />
|
|
|
|
</div> |
