feat(ui): add YAML format support for Extra Variables in Variable Groups - #4158
feat(ui): add YAML format support for Extra Variables in Variable Groups#4158thinas1115 wants to merge 8 commits into
Conversation
Adds a YAML option alongside the existing Table/JSON toggle for the extra variables editor (Ansible --extra-vars / Terraform -var). Input is parsed and converted to JSON on save via js-yaml, so the backend and stored format are unchanged. Resolves semaphoreui#319
Regenerated with npm 11.17.0 / Node 24 (matches CI's setup-node version) after adding js-yaml to package.json.
The JSON mode already had a RichEditor fullscreen expand button; YAML mode was missing it. Extends RichEditor to support a "yaml" type (CodeMirror YAML mode, js-yaml-based spellcheck) and wires it into the YAML editor for parity with the JSON mode.

the same as an empty document, silently replacing valid YAML values
with {} before they ever reached save/table conversion. Only an

changed the title
extraVarsEditMode's v-model already commits the new mode before the watcher runs, so a failed JSON/YAML parse when switching to Table left the mode stuck on 'table' with extraVars cleared. beforeSave() would then silently fall back to a stale this.json, saving the wrong data instead of surfacing the parse error. Revert extraVarsEditMode to the mode being left when parsing fails, guarding against the reverted assignment re-triggering the watcher.

objectToExtraVars() assumes a plain object: Object.keys(null) throws, and arrays/scalars silently become a wrong or empty table. Guard the same way in both places a non-object root could reach it -- switching to Table mode, and saving directly from YAML mode without ever switching modes (where the backend would otherwise accept a JSON "null" body as valid, silently discarding the user's input). Extracted the object-shape check into isPlainObject() since both guards need the identical condition.

Three issues from review: - The non-object guard only covered entering Table mode; switching YAML <-> JSON bypassed it entirely, letting a null/scalar/array root reach beforeSave() and the API unchecked. - isPlainObject() accepted any non-null, non-array object, including a Date (YAML auto-parses unquoted timestamps into these), which then produced a silently empty table. - A YAML anchor/alias cycle produces a genuinely circular JS object; JSON.stringify on it (directly, or nested inside objectToExtraVars) throws uncaught. Move the plain-object check before dispatching on the target mode so it applies to every transition, tighten it to require a plain Object.prototype (excluding Date etc.), and wrap the whole dispatch in one try/catch so any conversion failure -- known or not -- reverts to the previous mode with an error instead of crashing. Extracted the revert-and-suppress sequence into revertExtraVarsMode() since it's now used in five places, and aligned its error message with the existing one in beforeSave().

Two more gaps in extra-variables value handling, found while re-auditing after the previous fix: - js-yaml's default schema auto-converts unquoted timestamps (e.g. 2024-01-01) to JS Date objects at any nesting depth, not just the document root. This silently mangled values on save (Date -> full ISO string) and misclassified them as "dict" in Table mode (Date is typeof 'object'). JSON_SCHEMA only resolves the types JSON itself can represent, so timestamps stay plain strings throughout. - JSON_SCHEMA still resolves .inf/-.inf/.nan to real Infinity/NaN numbers (JSON has no such literals). JSON.stringify doesn't throw for these -- it silently writes "null", discarding the value. isJsonSafeValue() recursively rejects them before serialization, in both the watcher and beforeSave().

--extra-vars/-var). TheEnvironment Variables (process env) section currently has no raw
JSON/YAML editor of its own in the current UI, so it's left untouched to
keep this change focused.
Background
A previous attempt (#1652) implemented this for the pre-2024 version of
EnvironmentForm.vue, but the component has since been substantiallyrewritten (Table/JSON toggle,
RichEditor, secret storage sync, etc.), sothat PR no longer applies cleanly and has been sitting with merge conflicts
against
developfor two years. This PR reimplements the feature againstthe current component. Posted about this on #319 before opening this PR.
Changes
web/package.json/web/package-lock.json: addjs-yamldependency.web/src/components/EnvironmentForm.vue: add the YAML toggle option, aCodeMirror YAML editor, and Table⇄JSON⇄YAML conversion logic (each mode's
contents are re-derived from whichever mode was last edited).
web/src/components/RichEditor.vue: add a "yaml" type (YAML CodeMirrormode, js-yaml-based spellcheck) so the fullscreen expand editor works for
YAML too.
web/src/lang/en.js: addenterExtraVariablesYamlplaceholder string(other locales fall back to English via
fallbackLocale: 'en').Testing
npx eslinton the changed components: 0 errors / 0 warnings.npm run build: succeeds; only pre-existing warnings unrelated to thischange.
Verified end-to-end against a real, non-mocked build:
go run cli/main.go server, freshly migrated SQLite databasenpm run build), served fromapi/publicverify conversion to JSON and to the Table view and back → save → reload
→ confirm the saved YAML round-trips correctly
nested dict (with a further nested list inside it), and YAML-ambiguous
strings (
"no","yes", a key named"n", an empty string, a stringcontaining
": ") — all round-tripped JSON → YAML → JSON to an exactmatch, and
js-yamlcorrectly quoted the ambiguous scalars so they don'tget misread as booleans (the classic "Norway problem")
