DevLogBus

Examples

These examples assume devlogbusd is running with the default HTTP listener:

devlogbusd run

Open the browser UI:

http://127.0.0.1:7423/

Go slog

See examples/go-slog/main.go.

Run from the repository:

go run ./examples/go-slog

The example uses pkg/sloghandler so normal log/slog records publish to DevLogBus without changing call sites.

C

See sdk/c/examples/basic.c.

Build and run from the repository:

cmake -S sdk/c -B sdk/c/build
cmake --build sdk/c/build
./sdk/c/build/devlogbus_c_basic

The example uses the C SDK source package under sdk/c.

.NET / C#

The SDK source package lives under sdk/dotnet.

Use the client directly from a .NET app:

using DanSherwin.DevLogBus;

var devlog = new DevLogBusClient(new DevLogBusClientOptions
{
    Source = "checkout_api",
});

await devlog.PublishMessageAsync(
    "INFO",
    "checkout started",
    new Dictionary<string, object?> { ["requestId"] = "req-1" });

Run the SDK test program from the repository when the .NET SDK is installed:

dotnet run --project sdk/dotnet/DevLogBus.Sdk.Tests

Rust

See sdk/rust/examples/basic.rs.

Run from the repository:

cargo run --manifest-path sdk/rust/Cargo.toml --example basic

The example uses the Rust SDK source package under sdk/rust.

Java/Kotlin

See sdk/jvm/examples/Basic.java.

Build and run from the repository:

mkdir -p sdk/jvm/build/classes
javac -d sdk/jvm/build/classes \
  $(find sdk/jvm/src/main/java sdk/jvm/examples -name '*.java')
java -cp sdk/jvm/build/classes Basic

The example uses the Java-first JVM SDK source package under sdk/jvm. Kotlin code can call the same public classes directly.

Node/TypeScript

See examples/node-typescript/devlogbus.ts.

Run with a TypeScript runner:

npx tsx examples/node-typescript/devlogbus.ts

The example uses the SDK source package under sdk/node.

Python

See examples/python/devlogbus_example.py.

Run:

python3 examples/python/devlogbus_example.py

The example uses the SDK source package under sdk/python.

Browser/React Workflow

See examples/browser-workflow/index.html.

Open the file in Chrome or serve it with any local static server. Attach Browser Tap to the tab, then click the buttons. DevLogBus should show:

• direct browser console records from Browser Tap
• runtime exception records from Browser Tap
• network request/response records from Browser Tap
• one direct HTTP record posted by the page itself

This is the core DevLogBus workflow: application records, browser console records, runtime failures, and network records visible in one timeline.

Direct HTTP Publish

Publish one record with curl:

curl -X POST http://127.0.0.1:7423/api/records \
  -H 'Content-Type: application/json' \
  -d '{"level":"info","source":"curl","message":"hello from curl"}'

Publish a Browser Tap-shaped record:

curl -X POST http://127.0.0.1:7423/api/records \
  -H 'Content-Type: application/json' \
  -d '{
    "level": "warn",
    "source": "chrome:api.localhost:8080",
    "message": "GET /api/orders -> 500",
    "attrs": {
      "sourceGroup": "chrome:localhost:5173",
      "tabTitle": "Local Checkout",
      "status": 500
    }
  }'
