📝 Walkthrough

Walkthrough

Nitro now auto-generates Cloudflare cron triggers from configured scheduledTasks at build time; docs updated to describe this and implementation adds schedules into wrangler.json. A test verifies the generated cron entry.

Changes

Cohort / File(s)	Summary
Documentation Updates docs/1.docs/50.tasks.md, docs/2.deploy/20.providers/cloudflare.md	Updated tasks docs and provider docs to document auto-generation of Cloudflare cron triggers and note Wrangler config is handled at build time.
Cloudflare Preset Implementation src/presets/cloudflare/utils.ts	Added logic to collect scheduledTasks schedules, ensure wranglerConfig.triggers.crons exists, deduplicate against existing crons, and append new schedules before writing wrangler.json.
Test Coverage test/presets/cloudflare-module.test.ts	Added test asserting wrangler.json contains the generated triggers.crons entry (e.g., ["* * * * *"]).

90-91: Inconsistent dash style with the adjacent Vercel line.

Line 90 uses a hyphen-with-spaces (-) while line 91 uses an em-dash (—). Consider aligning for consistency.

✏️ Proposed fix

-- `cloudflare_module` preset has native integration with [Cron Triggers](https://developers.cloudflare.com/workers/configuration/cron-triggers/). Nitro automatically generates the cron triggers in the wrangler config at build time - no manual wrangler setup required.

In `@src/presets/cloudflare/utils.ts`:
- Around line 292-304: The cron injection block is running for both Pages and
Workers targets; restrict it to Workers module builds by checking the Cloudflare
target before mutating wranglerConfig.triggers. Wrap the existing condition that
checks nitro.options.experimental.tasks and nitro.options.scheduledTasks so it
also requires cfTarget === 'module' (or the variable used for the target in this
file), ensuring wranglerConfig.triggers and its crons are only modified for the
"module" target and not for Pages.
