ZIO Interop Log4J2\n[![Latest

Snapshot](https://img.shields.io/nexus/s/com.github.mlangc/zio-interop-log4j2_2.13?label=latest-snapshot\u0026server=https%3A%2F%2Foss.sonatype.org)](https://oss.sonatype.org/content/repositories/snapshots/com/github/mlangc/zio-interop-log4j2_2.13/)\n\nThis library provides ZIO fiber aware MDC logging for Log4j 2.\n\n## Usage\n1. Add `libraryDependencies += \"com.github.mlangc\" %% \"zio-interop-log4j2\" % version` to your `build.sbt`\n1. Add `-Dlog4j2.threadContextMap=com.github.mlangc.zio.interop.log4j2.FiberAwareThreadContextMap` to your JVM startup parameters. If you can't,\n  try to set the `log4j2.threadContextMap` system property programmatically as early as you can. The property must be set before Log4j2 is\n  initialized.\n1. Integrate `com.github.mlangc.zio.interop.log4j2.FiberAwareThreadContextMap.assertInitialized` into your initialization code. Fiber aware MDC\n   logging will not work properly without this call.\n1. Use `org.slf4j.MDC` as you would normally and observe that it now respects fiber boundaries.\n1. If you start getting annoyed by wrapping interactions with `MDC` in ZIO effects, take a look at [slf4zio](https://github.com/mlangc/slf4zio)\n   which ships an `MDC` convenience wrapper for ZIO called `MDZIO`.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmlangc%2Fzio-interop-log4j2","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmlangc%2Fzio-interop-log4j2","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmlangc%2Fzio-interop-log4j2/lists"}
