Okay, all done. You can now use #LogTape to send logs directly to the #OpenTelemetry collector!

I'm implementing an #OpenTelemetry sink for #LogTape, but it's more complicated than I thought and has a lot of package dependencies… 🤔

In the next version of #LogTape, a zero-dependency #logging library for #JavaScript & #TypeScript, contexts will be introduced that allow the same set of properties to be shared across multiple log messages. Thanks to @okikio for collaborating on the design! This feature is available for preview in 0.5.0-dev.60+f819929c.

• JSR: https://jsr.io/@logtape/[email protected]dev.60+f819929c
• npm: https://www.npmjs.com/package/@logtape/logtape/v/0.5.0-dev.60

https://github.com/dahlia/logtape#contexts

const logger = getLogger(["my-app", "my-module"]);
const ctx = logger.with({ userId: 1234, requestId: "abc" });
ctx.info `This log message will have the context (userId & requestId).`;
ctx.warn("Context can be used inside message template: {userId}, {requestId}."); — const logger = getLogger(["my-app", "my-module"]); const ctx = logger.with({ userId: 1234, requestId: "abc" }); ctx.info `This log message will have the context (userId & requestId).`; ctx.warn("Context can be used inside message template: {userId}, {requestId}.");

Released v0.4.2 of #LogTape, which is a zero-dependency #logging library for #TypeScript & #JavaScript! Since this version, it work well on #Cloudflare Workers out of box!

#Fedify offers robust logging capabilities through integration with LogTape. This feature allows you to easily debug and monitor your Fedify app!

To enable #logging, simply install the @logtape/logtape package and configure it in your app's entry point:

import { configure, getConsoleSink } from "@logtape/logtape";

await configure({
  sinks: { console: getConsoleSink() },
  filters: {},
  loggers: [
    { category: "your-app", sinks: ["console"], level: "debug" },
    { category: "fedify",   sinks: ["console"], level: "info" },
  ],
});

Fedify uses hierarchical categories for fine-grained control over log output. Key categories include ["fedify", "federation", "http"] for HTTP requests/responses and ["fedify", "federation", "inbox"]/["fedify", "federation", "outbox"] for incoming/outgoing activities. (There are more categories.)

With #LogTape integration, you gain valuable insights into your Fedify app's behavior, making troubleshooting and optimization much more straightforward!
