fastlog/middlewares
Import path: github.com/InsideGallery/core/fastlog/middlewares
middlewares contains reusable slog middleware for fastlog pipelines.
Main APIs
CallerMiddlewareadds acallerattribute infile:lineform while preserving existing attributes.ErrorFormattingMiddlewareconverts anerrorattribute holding anerrorvalue into a group withtypeandmessagefields.NewGDPRMiddleware()returns a handler middleware that masks exact keyspassword,email, andphonewith*******.
Usage
package example
import (
"github.com/InsideGallery/core/fastlog"
"github.com/InsideGallery/core/fastlog/middlewares"
)
func configureLogging() error {
cfg, err := fastlog.GetConfigFromEnv()
if err != nil {
return err
}
return fastlog.SetupDefaultLogger(cfg, middlewares.NewGDPRMiddleware())
}
Operational Notes
fastlog.Config wires CallerMiddleware from LOG_CALLER and ErrorFormattingMiddleware from
LOG_ERROR_FORMATTING. Custom middleware passed to GetHandler or SetupDefaultLogger runs after those built-in
middlewares.
The GDPR middleware masks matching top-level attributes, attributes added through WithAttrs, and nested group
attributes when the group name or attribute key is one of the configured PII keys.
