interface OutputProvider<App>

Type parameters

Type parameter	Constraint	Default type
App	—	—

Field structure

Field	Type	Required	Description
id	string	Required	Read-only. See the type definition and usage context.
resolve	(request: { readonly key?: string; }, context: OperationContext<App>) => unknown	Required	Produces the value; key carries the selected semantic key, when there is one.

Member index

Member	Purpose
resolve	Produces the value; key carries the selected semantic key, when there is one.

Member details

resolve

Produces the value; key carries the selected semantic key, when there is one.

OutputProvider.resolve(request: { readonly key?: string; }, context: OperationContext<App>): unknown

Produces the value; key carries the selected semantic key, when there is one.

Parameter	Type	Passing	Description
request	{ readonly key?: string; }	Required	—
context	OperationContext<App>	Required	—

Fields of request

Field	Type	Required	Description
key	string | undefined	Optional	Read-only. See the type definition and usage context.

Fields of context

Field	Type	Required	Description
app	unknown extends App ? App : Readonly<App>	Required	Read-only. See the type definition and usage context.
logger	SubFlowLog | undefined	Optional	Read-only. Explicit optional recorder for this operation; never inferred from diagnostics.
signal	AbortSignal	Required	Read-only. Non-optional cancellation signal; never undefined once execution has started.
diagnostics	DiagnosticContext | undefined	Optional	Read-only. Diagnostic scope of the enclosing call, when recording is enabled.

Returns: unknown.

Examples

• Presentation: field ownership and final output: The model fills only the fields it is assigned; fixed text, bound values, and semantic keys are owned by the program.

First compose one piece of generated text

Beginner · Node.js

TypeScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
const outputs = Presentation.defineOutputCatalog([
  { id: 'reply', kind: 'text', fields: [{ id: 'text', owner: 'generated' }] },
]);
console.log(outputs.toModelSchema('reply'));
const output = outputs.compose({ outputId: 'reply', input: { generated: { text: '普通对象即可定义节点。' } } }, { app: {}, signal: new AbortController().signal });
console.log(output.value);

JavaScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
const outputs = Presentation.defineOutputCatalog([
    { id: 'reply', kind: 'text', fields: [{ id: 'text', owner: 'generated' }] },
]);
console.log(outputs.toModelSchema('reply'));
const output = outputs.compose({ outputId: 'reply', input: { generated: { text: '普通对象即可定义节点。' } } }, { app: {}, signal: new AbortController().signal });
console.log(output.value);

Let the program own the explanatory prefix in the same compose

Configuration · Node.js

TypeScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
const outputs = Presentation.defineOutputCatalog([
  { id: 'reply', kind: 'master', master: '{{prefix}}{{text}}', fields: [
    { id: 'prefix', owner: 'constant', constantValue: '接口说明：' },
    { id: 'text', owner: 'generated' },
  ] },
]);
console.log(outputs.toModelSchema('reply')); // 只有 text 由模型填写
console.log(outputs.compose({ outputId: 'reply', input: { generated: { text: '普通对象即可定义节点。' } } }, { app: {}, signal: new AbortController().signal }).value);

JavaScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
const outputs = Presentation.defineOutputCatalog([
    { id: 'reply', kind: 'master', master: '{{prefix}}{{text}}', fields: [
            { id: 'prefix', owner: 'constant', constantValue: '接口说明：' },
            { id: 'text', owner: 'generated' },
        ] },
]);
console.log(outputs.toModelSchema('reply')); // 只有 text 由模型填写
console.log(outputs.compose({ outputId: 'reply', input: { generated: { text: '普通对象即可定义节点。' } } }, { app: {}, signal: new AbortController().signal }).value);
