prisma-axiom

Axiom observability middleware for Prisma.

Quickstart

1. Install prisma-axiom

npm install --save prisma-axiom

2. Wrap your main functions in withAxiom to automatically set up telemetry and flush traces before exit.

import withAxiom from 'prisma-axiom';
const prisma = new PrismaClient();

async function main() {
  // do something with prisma
}

withAxiom(main)() // wrap function 

Note: This will configure Axiom from the AXIOM_TOKEN and other environment variables. Check out the Kitchen Sink Full Configuration for more advanced configuration.

3. Enable the prisma tracing preview feature in schema.prisma like this:

generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["tracing"]
}

Kitchen Sink Full Configuration

Import and use withAxiom to automatically setup & configure OpenTelemetry with the Prisma instrumentation sending traces to Axiom.

You can configure prisma-axiom by passing an options object as the second parameter to withAxiom.

This snippet shows all available options:

const myFn = withAxiom(myFn, {
  axiomToken:                 "xaat-xxxxx",
  axiomUrl:                   "https://my-axiom.example.org",
  additionalInstrumentations: [new HttpInstrumentation()] // add more instrumentations to the tracing setup
});

Custom Configuration

When you have your OpenTelemetry setup you can use the Axiom's exporter, and attach it to the provider. See the extend-otel example for more details.

The exporter can automatically retreive the Axiom token and url variables from AXIOM_URL and AXIOM_TOKEN respectively, but they can also be passed as parameters.

This is what it could look like:

import { axiomTraceExporter } from 'prisma-axiom';

const provider = new NodeTracerProvider({
  resource: new Resource({
    [SemanticResourceAttributes.SERVICE_NAME]: process.env.npm_package_name,
    [SemanticResourceAttributes.SERVICE_VERSION]: process.env.npm_package_version,
  }),
})

// create axiom's exporter object and add a new span processor:
const exporter = axiomTraceExporter();
provider.addSpanProcessor(new BatchSpanProcessor(exporter));
provider.register()

registerInstrumentations({
  instrumentations: [new PrismaInstrumentation(), new HttpInstrumentation()],
});

function main () {
  // ...
}

// shutdown the provider to ensure delivery
main().finally(async () => {
  await provider.shutdown()
})

FAQ & Troubleshooting

I don't get any traces

Enable tracing preview in Prisma

As tracing support for Prisma is in preview, you need to explicitly enable it. See Quickstart step 3, schema.prisma has to be altered like this:

generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["tracing"]
}

Also note that this preview feature is only available starting with Prisma v4.2.0.
