Lifecycle Hooks

PtahJs exposes a synchronous pipeline through runtime.lifecycleChain.

Basic Usage

import { useRuntimeApp } from '@ptahjs/ui-vue';
import { LIFECYCLE_TYPE } from '@ptahjs/kernel';

const runtime = useRuntimeApp({ id: 've1' });

runtime.lifecycleChain.addStep(LIFECYCLE_TYPE.GET_PAGE_SCHEMA_DATA, (data) => {
    return { ...data, exportedAt: Date.now() };
});

API

Method	Description
addStep(type, fn)	Register a step
removeStep(type, fn)	Remove a step
clearSteps(type)	Clear steps by type
clearAll()	Clear all steps
process(type, data)	Execute the pipeline

Lifecycle Types

• BEFORE_TRANSFORM_DATA
• GET_PAGE_SCHEMA_DATA
• RENDERER_MODULE_CONTENT
• RENDERER_MODULE_ITEM

Notes

• Steps run synchronously
• Steps run in registration order
• Returning undefined keeps the previous value
• Returning a Promise is ignored by the runtime

Example

runtime.lifecycleChain.addStep(LIFECYCLE_TYPE.BEFORE_TRANSFORM_DATA, (schema) => {
    return schema;
});
