Make ~/.devspace/config.jsonc the single durable configuration source, backed by Zod and a generated versioned JSON Schema. devspace config set preserves comments, the schema ships in the npm package, and only the config-directory bootstrap plus OAuth secret override remain as user-facing DevSpace environment variables.

When JSONC is absent, a valid v1.0 config.json is migrated once through a validated temporary file and the original is renamed to config.json.v1.0.bak. Existing or invalid JSONC never falls back. The full test suite, production build, schema convergence check, and npm package-content check pass.

📝 Walkthrough

Walkthrough

DevSpace now uses a versioned JSONC configuration system. It validates settings with Zod, supports legacy config.json migration, updates CLI and daemon wiring, and replaces environment-based test fixtures and documentation.

Changes

Configuration schema and packaging

Layer / File(s) Summary
Versioned schema and generation
schema/v1/devspace.schema.json, src/config-schema.ts, scripts/generate-config-schema.ts, src/config-schema.test.ts, package.json
Defines the strict v1 configuration schema, generates the published JSON Schema, validates schema consistency, and adds jsonc-parser.
JSONC persistence and migration
src/user-config.ts, src/config-migration.ts, src/user-config.test.ts
Loads and writes config.jsonc, preserves comments during updates, validates values, and migrates legacy config.json files with backups and race-safe publication.
Runtime and daemon integration
src/config.ts, src/cli.ts, src/local-agent-config.ts, src/local-agent-client.ts
Reads nested persisted settings, updates server.publicBaseUrl, resolves subagents from stored configuration, and passes DEVSPACE_CONFIG_DIR to local-agent daemons.
Test fixture migration
src/test-support/config.test.ts, src/*test.ts
Uses generated structured configuration files across CLI, server, skills, workspace, profile, conversation, and configuration tests.
Documentation and CI updates
.github/workflows/ci.yml, docs/*.md
Replaces removed environment-variable instructions with config.jsonc settings and updates CI smoke-job configuration.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to 8cf4f

The configuration migration is broadly mergeable, but forced initialization can discard a stored tunnel URL, editor schema validation may fail because the published schema location is unreachable, migration conflicts provide insufficient recovery guidance, and some tooling depends on the current working directory. These bounded issues should be fixed or explicitly accepted by the owner.

Poem

A rabbit hops through JSONC bright,
With schemas guarding every byte.
Old config files find a new home,
While daemons learn where paths should roam.
Tests plant settings, neat and clear—
And docs now point the proper ear.

Greptile Summary

This PR replaces the legacy flat JSON/environment configuration model with a validated, versioned JSONC configuration and adds automatic migration, schema generation, comment-preserving updates, and daemon configuration propagation.

  • Adds strict nested configuration schemas, defaults, and a published JSON Schema.
  • Migrates legacy config.json into config.jsonc while retaining a backup.
  • Moves durable runtime settings from environment variables into JSONC and updates CLI, documentation, daemon startup, and tests.
  • Preserves JSONC comments when updating publicBaseUrl.

Confidence Score: 4/5

The migration race should be fixed before merging because concurrent first-start commands can cause one otherwise valid invocation to fail.

The new configuration model is internally aligned across schema, runtime loading, CLI, and daemon startup, but legacy migration is not idempotent when multiple processes perform the first load concurrently.

Files Needing Attention: src/user-config.ts

Important Files Changed

Filename Overview
src/user-config.ts Implements JSONC loading, atomic writes, comment-preserving edits, and legacy migration; concurrent first loads can make one valid invocation fail.
src/config-schema.ts Defines the strict versioned nested configuration schema, defaults, and generated JSON Schema representation.
src/config-migration.ts Validates and translates supported legacy fields, including legacy boolean subagent configuration.
src/config.ts Builds runtime configuration from validated JSONC plus the retained owner-token environment override.
src/local-agent-client.ts Propagates the active configuration directory when spawning the detached local-agent daemon.
src/cli.ts Updates onboarding, configuration commands, migration reporting, and help text for the JSONC model.
schema/v1/devspace.schema.json Publishes the generated draft-2020-12 editor schema for version-one DevSpace configuration.

242-242: 🗄️ Data Integrity & Integration | 🔵 Trivial | 🏗️ Heavy lift

init discards comments in config.jsonc.

writeDevspaceConfig serializes the parsed object with JSON.stringify and replaces the file, so devspace init --force removes every comment. devspace config set preserves comments through setDevspaceConfigValue. The two write paths give the user different guarantees for the same file.

Consider applying the init result through targeted JSONC edits, or document that init rewrites the document.

Both sites locate the generated schema through the process working directory. resolve() on a relative path only works when the command runs from the package root, so generation and the drift check can silently target the wrong file.

reachable at its configured URL by publishing schema/v1/devspace.schema.json on
the main branch; alternatively, update DEVSPACE_CONFIG_SCHEMA_URL and the
generated documentation to use an existing reachable location, while keeping
devspace init’s generated $schema reference consistent.

- Around line 226-231: Update the server configuration construction around
publicBaseUrl so it preserves the persisted files.config.server.publicBaseUrl
when the ChatGPT selection flow does not run and the local publicBaseUrl remains
null; only overwrite it when a new value was provided.

state the required user recovery action, while preserving the existing paths and

[GPT-5] RESPONDING ON BEHALF OF WAISHNAV

Addressed both review-summary nits in separate commits:

  • d5ef719 makes init update only the configuration fields it owns through a single validated atomic JSONC edit, preserving unrelated comments.
  • 3f4ff9e anchors schema generation and drift checks to import.meta.url, so neither depends on the caller working directory.

Full tests, typecheck, build, and package dry-run pass locally.
