SchemaIssue.makeFormatterDefault

Creates a Formatter that converts an Issue into a human-readable multi-line string.

When to use

Use when you need to format a SchemaIssue.Issue as error messages for logging, CLI output, or developer-facing diagnostics.

Details

This is the default formatter used by SchemaIssue.toString().

• Flattens the issue tree into { message, path } entries using defaultLeafHook and defaultCheckHook.
• Each entry is rendered as "<message>" or "<message>\n at <path>".
• Multiple entries are joined with newlines.

Example (Formatting an issue as a string)

import { SchemaIssue } from "effect"

const formatter = SchemaIssue.makeFormatterDefault()
