Definition

Call

textOutputEvents(chunks: AsyncIterable<string>): AsyncIterable<AgentOutputEvent>

Wrap already-chunked text as text events.

Parameter	Type	Passing	Description
chunks	AsyncIterable<string>	Required	—

Returns: AsyncIterable<AgentOutputEvent>.

Examples

• Reply events: text chunks and bubble boundaries: Turn an accepted reply into awaitable text/bubble events while preserving cancellation and delivery backpressure.

First output a reply that is already accepted

Beginner · Node.js

TypeScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
const context = { signal: new AbortController().signal };
for await (const event of Presentation.publishReplyEvents({ text: '这是已经接受的答复。' }, context)) console.log(event);

JavaScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
const context = { signal: new AbortController().signal };
for await (const event of Presentation.publishReplyEvents({ text: '这是已经接受的答复。' }, context))
    console.log(event);

Add chunking and bubbles to the same event entry

Configuration · Node.js

TypeScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
const text = Presentation.replyBubbleTexts({ text: '先说明定义。', bubbles: ['再解释输入输出。'] }).join(Presentation.REPLY_BUBBLE_BOUNDARY);
const events = Presentation.publishReplyEvents({ text, delivery: { chunkSize: 6, intervalMs: 10, bubblePauseMs: 30, maxDurationMs: 1000 } }, { signal: new AbortController().signal });
for await (const event of events) {
  if (event.type === 'text') process.stdout.write(event.text);
  else if (event.type === 'bubble') process.stdout.write('\n');
}

JavaScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
const text = Presentation.replyBubbleTexts({ text: '先说明定义。', bubbles: ['再解释输入输出。'] }).join(Presentation.REPLY_BUBBLE_BOUNDARY);
const events = Presentation.publishReplyEvents({ text, delivery: { chunkSize: 6, intervalMs: 10, bubblePauseMs: 30, maxDurationMs: 1000 } }, { signal: new AbortController().signal });
for await (const event of events) {
    if (event.type === 'text')
        process.stdout.write(event.text);
    else if (event.type === 'bubble')
        process.stdout.write('\n');
}

Convert an existing text stream within the same contract

Extension · Node.js

TypeScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
async function* chunks() { yield '已接受的'; yield '正文。'; }
const events = Presentation.textOutputEvents(chunks());
for await (const text of Presentation.serializeOutputEvents(events)) console.log(text);

JavaScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
async function* chunks() { yield '已接受的'; yield '正文。'; }
const events = Presentation.textOutputEvents(chunks());
for await (const text of Presentation.serializeOutputEvents(events))
    console.log(text);
