feat(compiler): make the AI request timeout configurable - #2192
Conversation
📝 WalkthroughWalkthroughAdds the ChangesAI timeout configuration
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk:🔵 Low · up to The change makes AI request timeouts configurable and raises the default to 120 seconds. It is mergeable with owner awareness because the documentation should clarify the doubled pluralization timeout and that timed-out requests may still be billed; these are bounded follow-ups rather than runtime blockers.

Document that timed-out requests can still incur charges.
The API documentation states that a timeout does not cancel the AI request and that the request can still be billed. Add this behavior here so users do not lower aiTimeout expecting cancellation or cost avoidance.

Clarify the effective pluralization timeout.
This documentation defines aiTimeout as the batch timeout. PluralizationService doubles every configured value at line 170. Therefore, aiTimeout: 300_000 produces a 600000ms timeout.
Describe this field as a base timeout, or stop doubling an explicit pluralization value.
Proposed documentation fix
- * Milliseconds to wait for a pluralization batch. Defaults to twice the- * translation timeout, since a batch asks the model for more at once.+ * Base timeout in milliseconds for a pluralization AI request.+ * A pluralization batch uses twice this value because it sends more data.📝 Committable suggestion

Closes#2053.
Problem
The timeout for a single AI translation request is hardcoded at 60 seconds (
DEFAULT_TIMEOUTS.AI_API). It is not enough when the build runs somewhere with slow network to the model, such as CI, or when a chunk carries enough text that the model needs longer, and a compiler chunk goes to the model as one call regardless of how much text it holds.The documented workaround in #2053 is patching the compiled file inside
node_modules:Change
aiTimeoutis a new plugin option, threaded fromLingoConfigthroughTranslationServiceintoLingoTranslator, and applied on both the Lingo.dev Engine and the direct-LLM paths.DEFAULT_TIMEOUTS.AI_APIstays as the fallback for callers that pass nothing, and is raised to match.LingoPluginOptionsandLingoNextPluginOptionsare aliases ofPartialLingoConfig, so Vite, webpack and Next pick the option up.Why the default moved rather than staying at 60s
A request that times out is not cancelled.
withTimeoutis aPromise.race, so the underlying call keeps running server-side, completes, and is billed, while its result is discarded. A timeout that fires too eagerly therefore costs money, not just build time. Waiting longer makes it more likely the caller actually receives the work it paid for.This does not make the timeout harmless, and this PR does not claim to fix the billing side. Cancelling the abandoned request needs the
signalthatLingoDotDevEngine.localizeObjectalready accepts as its fourth parameter and threads intofetch; wiring that up is separate work.Tests
Two, driving the real
withTimeoutthrough the real translator with only the SDK engine stubbed to hang, and fake timers advancing the clock:aiTimeoutof 300000 is still pending at the 120000 mark and rejects at 300000aiTimeout, it rejects at the defaultVerified the first fails without the wiring. Full package suite:
