Define the Schema + +```typescript +const argsSchema = defineSchema({ + type: "object", + properties: { + createPreview: { type: "boolean" }, + }, + required: [], // Optional - allows workflow to run without arguments +}); +``` + +This creates a type-safe schema that: +- Defines `createPreview` as a boolean +- Makes it optional (not in `required` array) +- Provides TypeScript autocomplete for `event.data.args.createPreview` + +### 2. Conditional Execution + +```typescript +const { createPreview } = event.data.args; + +if (!createPreview) { + await step.annotation("skip-preview", { + message: "⏭️ Preview skipped", + }); + return; +} + +const preview = await step.preview("deploy"); +``` + +The workflow checks the argument and: +- Skips preview when `false` or `undefined` +- Runs preview when `true` +- Annotates the decision for visibility + +### 3. Graceful Docker Handling + +```typescript +const preview = await step.preview("deploy"); + +if (Object.keys(preview.data.urls).length === 0) { + // Docker not available + await step.annotation("no-docker", { + message: "⚠️ Preview skipped - Docker not available", + }); + return; +} + +// Docker available - use preview.data.urls.app +``` + +When Docker is unavailable, `step.preview()` succeeds but returns empty URLs. Check the URLs object to handle this gracefully. + +## Common Patterns + +### Multiple Preview Configurations + +```typescript +const argsSchema = defineSchema({ + type: "object", + properties: { + createPreview: { type: "boolean" }, + previewType: { enum: ["development", "staging", "production"] }, + }, +}); + +// In workflow +if (createPreview) { + const { previewType } = event.data.args; + + const preview = await step.preview("deploy", { + env: { + NODE_ENV: previewType || "development", + }, + }); +} +``` + +### Conditional Resource Allocation + +```typescript +const argsSchema = defineSchema({ + type: "object", + properties: { + createPreview: { type: "boolean" }, + highPerformance: { type: "boolean" }, + }, +}); + +// In workflow +if (createPreview) { + const { highPerformance } = event.data.args; + + const preview = await step.preview("deploy", { + maxMemory: highPerformance ? "4g" : "1g", + maxCpus: highPerformance ? "2.0" : "0.5", + }); +} +``` + +### Preview with Testing + +```typescript +await step.phase("preview", async () => { + if (!createPreview) { + await step.annotation("skip-preview", { + message: "⏭️ Preview and tests skipped", + }); + return; + } + + const preview = await step.preview("deploy"); + + if (Object.keys(preview.data.urls).length === 0) { + return; // Docker unavailable + } + + // Run E2E tests against preview + await step.cli("e2e-tests", { + command: `PREVIEW_URL=${preview.data.urls.app} pnpm test:e2e`, + }); + + await step.annotation("tests-complete", { + message: `✅ E2E tests passed against ${preview.data.urls.app}`, + }); +}); +``` + +## Use Cases + +**Development Workflows**: +- Skip preview for simple bug fixes +- Enable preview for new features +- Toggle based on PR size + +**CI/CD Integration**: +- Preview for feature branches only +- Skip preview on hotfix branches +- Conditional based on labels + +**Cost Optimization**: +- Disable preview for documentation changes +- Enable only for frontend changes +- Resource allocation based on priority + +**Team Workflows**: +- Junior devs always get preview +- Senior devs opt-in for preview +- Preview required for specific file patterns + +## Best Practices + +**Default to the safest option**: +```typescript +// Preview is opt-in, not opt-out +const { createPreview } = event.data.args; +if (!createPreview) return; +``` + +**Provide clear feedback**: +```typescript +await step.annotation("skip-preview", { + message: "⏭️ Preview skipped (createPreview=false)\n\nTo enable: check 'Create Preview' when running workflow", +}); +``` + +**Handle all edge cases**: +```typescript +if (!createPreview) { + // Explicitly skipped + return; +} + +const preview = await step.preview("deploy"); + +if (Object.keys(preview.data.urls).length === 0) { + // Docker unavailable + return; +} + +// Happy path - preview running +``` + +**Document the argument**: +```typescript +export default defineWorkflow( + { + id: "preview-deployment-workflow", + description: "Set createPreview=true to deploy Docker preview container", + argsSchema, + }, + async ({ event, step }) => { + // ... + } +); +``` + +## Next Steps + +- [Type-Safe Arguments](/docs/examples/type-safe-arguments) - Complete guide to workflow arguments +- [Preview Step Reference](/docs/reference/workflow-steps/preview) - Full preview configuration options +- [Context Sharing](/docs/examples/context-sharing) - Share data between phases +- [Implement & Review](/docs/examples/implement-and-review) - Complete implementation workflow diff --git a/apps/website/content/docs/examples/type-safe-arguments.mdx b/apps/website/content/docs/examples/type-safe-arguments.mdx index 56b558a2..18b73631 100644 --- a/apps/website/content/docs/examples/type-safe-arguments.mdx +++ b/apps/website/content/docs/examples/type-safe-arguments.mdx @@ -77,6 +77,7 @@ Required fields are marked with an asterisk (\*) and validated before the workfl ## Next Steps +- [Preview Deployment](/docs/examples/preview-deployment) - Conditional preview with boolean arguments - [Context Sharing](/docs/examples/context-sharing) - Share data between phases - [Type-Safe Slash Commands](/docs/examples/type-safe-slash-commands) - Build reusable workflow commands - [Workflow Definition](/docs/concepts/workflows/workflow-definitions) - Back to basics diff --git a/apps/website/content/docs/reference/workflow-steps/preview.mdx b/apps/website/content/docs/reference/workflow-steps/preview.mdx index a208b42c..c754eaea 100644 --- a/apps/website/content/docs/reference/workflow-steps/preview.mdx +++ b/apps/website/content/docs/reference/workflow-steps/preview.mdx @@ -370,6 +370,9 @@ docker compose version ## Next Steps + + Conditional preview with type-safe arguments + Commit and push after preview testing
