📚 Description

evlog map and evlog logs read evlog.config.ts (or .mts, .js, .mjs), the nearest one from the package up to the workspace root. The CLI parses the file with oxc and never runs it.

import { defineEvlog } from 'evlog'
import base from '../../evlog.config'

export default defineEvlog({
  extends: base,
  env: { service: 'shop' },
  map: { ignore: ['src/internal/**'], rules: { 'error-handling': 'off' } },
  logs: { limit: 50 },
})

Setting	Read by	Behaves like
map.rules	evlog map	Turns a check off or back on for every entry point
map.ignore	evlog map	Leaves entry points out by file glob, and --json reports how many as ignored
map.minScore	evlog map	--min-score
map.baseline	evlog map	--baseline
logs.dir	evlog logs	--dir
logs.limit	evlog logs	--limit

A flag wins over the config. The config can extend a local file or a published preset, one level deep. extends takes the imported config, the same value the app merges at runtime, so a string path stops with CONFIG_EXTENDS_STRING.

evlog config prints the settings that apply and the file and line each one comes from, and --json prints the same as JSON. Output from this branch, for an app with two routed services that extends a base config:

evlog.config.ts · extends ./base/evlog.config → base/evlog.config.ts

Services · first matching route wins
  /api/auth/**          auth           evlog.config.ts:9
  /api/billing/v1.2/**  billing        evlog.config.ts:10
  any other route       shop           evlog.config.ts:7
  environment           from NODE_ENV  default

Sampling
  trace  0%      default
  debug  0%      base/evlog.config.ts:4
  info   10%     evlog.config.ts:14
  warn   100%    default
  error  100%    default
  fatal  always  default

Redaction
  redact    on                                                 evlog.config.ts:13
  builtins  creditCard, email, ipv4, phone, jwt, bearer, iban  default
  paths     user.email                                         base/evlog.config.ts:3
            card.number                                        evlog.config.ts:13

Pipeline
  drain  createAxiomDrain()  evlog.config.ts:12

CLI · read by evlog map and evlog logs
  map.rules.audit  'off'          base/evlog.config.ts:5
  logs.dir         '.evlog/logs'  evlog.config.ts:15

The output is grouped by what each setting does. Services follow route order, sampling lists every level with its default, a computed value shows its expression instead of its code, and --json keeps the flat cli and app lists.

evlog doctor reports a config it can't read. A misspelt setting, a value under map or logs computed at runtime, or turning off wide-event or context stops the command with a cli.CONFIG_* error (CONFIG_INVALID, CONFIG_NOT_STATIC, CONFIG_EXTENDS_DEPTH, CONFIG_EXTENDS_NOT_FOUND, CONFIG_EXTENDS_STRING, CONFIG_NO_EXPORT, CONFIG_PARSE_FAILED).

Decisions to review

• The @evlog/cli peer range for evlog moves to >=2.31.0, since the CLI imports mergeEvlogConfig from layer 1.
• Config paths (logs.dir, map.baseline) resolve from the analysed package, not from the config file.
• wide-event and context can't be turned off in map.rules. map.ignore is the way to skip an entry point.
• A preset's exports map is resolved in the package's own key order with the ESM conditions, and a package.json that doesn't parse counts as not found.

Not covered: map.ignore matches route files, not routes declared inline in one file.

Checks run: packages/cli 641 tests pass, tsc and the build are clean, content-lint scores 100 on the changed docs pages and changeset.

📝 Checklist

• I have linked an issue or discussion.
• I have updated the documentation accordingly.

📝 Walkthrough

📝 Walkthrough

Walkthrough

The CLI adds project configuration discovery, static reading, validation, and reporting. The map and logs commands apply supported settings, while doctor checks configuration validity. Documentation, telemetry fields, tests, and package metadata are also updated.

Changes

Project configuration

Layer / File(s)	Summary
Config reading, resolution, and validation packages/cli/src/lib/config/*, packages/cli/src/lib/errors.ts, packages/cli/test/config.test.ts, packages/cli/package.json, .changeset/cli-config.md	The CLI discovers and statically reads configuration, resolves imports and one parent config, validates map and logs settings, and records setting sources. Tests cover discovery, merging, and validation. The evlog peer minimum is now 2.31.0.
Config command and doctor diagnostics packages/cli/src/commands/config.ts, packages/cli/src/commands/doctor.ts, packages/cli/src/commands/index.ts, apps/docs/content/3.cli/{0.overview.md,6.doctor.md,11.config.md}, apps/telemetry/server/utils/allowed-tools.ts	The new evlog config command displays configuration and setting sources. doctor reports configuration read results. Documentation, telemetry allowlists, and tests cover these commands.
Map configuration behavior packages/cli/src/commands/map.ts, packages/cli/src/lib/map/*, packages/cli/test/{config.test.ts,map.command.test.ts,map/telemetry.test.ts}, apps/docs/content/3.cli/2.map.md, apps/telemetry/server/utils/allowed-tools.ts, .agents/skills/create-map-rule/SKILL.md, skills/review-logging-patterns/SKILL.md	Map configuration controls disabled rules, ignored entry points, baseline selection, and minimum-score gates. Reports identify configured settings and threshold sources. Scan results and telemetry include ignored-entry and configuration data.
Logs configuration behavior packages/cli/src/commands/logs.ts, packages/cli/src/lib/logs/query.ts, packages/cli/test/config.test.ts, apps/docs/content/3.cli/10.logs.md	The logs command uses configured directory and limit values as defaults. Explicit command-line options take precedence.

Tested config, map, logs and doctor against a Nuxt app whose evlog.config.ts extends a local base. map.ignore, map.rules, logs.limit and flag precedence (--limit 5 over logs.limit: 3) all work, and the extends ./evlog.base → evlog.base.ts line is great.

One small thing on provenance: arrays that mergeEvlogConfig concatenates are attributed only to the child. With redact: { paths: ['user.email'] } in the base and redact: { paths: ['card.number'] } in the app config, evlog config shows:

redact.paths   ['user.email', 'card.number']   evlog.config.ts:16

user.email comes from evlog.base.ts. For the concatenated keys (redact.paths, redact.patterns, sampling.keep), listing both locations, or splitting the entry by source, would keep the "where does this come from" promise.

[HugoRCD]

Fixed in 329e811, already on this branch. Appended lists (redact.paths, redact.patterns, sampling.keep) now get one row per item, each pointing at the file and line it comes from, so an item from the parent shows the parent's location. --json has one entry per index.

Re-tested on f52aef4. Per-file provenance for concatenated redact.paths is fixed (user.ssn cfg/base.ts:2, card.number evlog.config.ts:3), and the nuxt.config overrides are now shown with their source line. Thanks!

One thing in the new grouped output: with minLevel: 'warn' in the file, the Sampling section reads

Sampling
  trace     off, below minLevel  evlog.config.ts:3
  debug     off, below minLevel  evlog.config.ts:3
  info      off, below minLevel  evlog.config.ts:3
  warn      100%                 default

That suggests request events at info are dropped, but they are not. minLevel only applies to the global log API (7.reference/1.configuration.md: "not createLogger / request wide events"), and the same app keeps emitting INFO GET / 200 wide events. Someone reading evlog config to find out why they see info events, or why they don't, gets the wrong answer.

Suggestion: keep the rates as configured in the Sampling rows, and show minLevel on its own row with a short note, for example minLevel warn global log API only.

[HugoRCD]

Fixed in 0211fe7.

evlog config no longer shows off, below minLevel in the Sampling section. Every level now shows its real rate, because minLevel only gates the global log API and request wide events skip it. The minLevel row stays, with a line under it: applies to the global log API only, not request wide events.

Sampling
  debug     100%  default
  info      50%   evlog.config.ts:3
  ...
  minLevel  warn  evlog.config.ts:2
            applies to the global log API only, not request wide events

Covered by keeps the rates below minLevel, which only gates the global log API in packages/cli/test/config.test.ts. The rest of the stack is restacked on top.
