Description

This PR introduces built-in execution capabilities to the Playground, allowing users to test operations directly from the spec UI. By leveraging the new plugin architecture (PluginSlot.OPERATION), users can now fire actual HTTP requests and simulate Webhook payload deliveries seamlessly without needing to switch to external tools.

Changes proposed in this pull request:

  • Implemented a default HTTP execution plugin (httpPlugin) that detects HTTP bindings on operations and allows users to fire real HTTP requests inline via the Playground UI.
  • Implemented a default Webhook simulation plugin (webhookPlugin) that detects webhook operations and allows users to simulate payload delivery to a specified target endpoint.
  • Handled gracefully displaying request results (status codes, headers, and formatted response body) inline, as well as surfacing network/configuration errors cleanly.
  • Registered both plugins in the main Playground component using the new PluginSlot.OPERATION architecture, leaving standard/non-matching operations completely unaffected.

Resolves #1299

Summary by CodeRabbit

  • New Features
    • Added HTTP operation execution in the playground, including request handling, loading states, errors, and response details.
    • Added webhook simulation with configurable endpoints, generated sample payloads, delivery controls, and response feedback.
    • Enabled both HTTP and webhook tools in the playground’s AsyncAPI experience.

The new execution feature can send incorrect requests or become stuck, so its core HTTP and webhook behavior should be corrected before merge.

Inline comments:
In `@playground/app/page.tsx`:
- Line 98: Stabilize the plugin array passed to AsyncApi by defining the
[httpPlugin, webhookPlugin] collection once at module scope and reusing that
stable reference in the render output instead of creating it inline in
Playground.render().

In `@playground/components/plugins/ExecutionResult.tsx`:
- Around line 85-92: Update executeRequest and its callers so requests are
created within the component using an AbortSignal rather than receiving an
already-started Promise<Response>; add a bounded timeout that aborts the request
and clean up both the timeout and AbortController on completion or error. Add
unmount cleanup to abort any active request, ensuring parseAndSetResponse
cancellation also clears the loading state and does not leave actions disabled.
- Around line 3-5: Replace the explicit any on ExecutionResultProps.response
with a defined ExecutionResponse interface, and type parsed response data as
unknown wherever it is handled in the ExecutionResult component. Update the
component’s response access accordingly while preserving its existing behavior
and satisfying no-explicit-any.

In `@playground/components/plugins/HttpPlugin.tsx`:
- Around line 34-39: Update the fetch call in HttpPlugin to include a
schema-based operation payload for POST, PUT, and PATCH requests, while
preserving the current behavior for methods without request bodies. Add the
applicable Content-Type header, and ensure the payload is serialized in the
format expected by the operation.
- Line 22: Update the serverUrl selection in HttpPlugin so an empty servers
collection does not fall back to globalThis.location.origin; instead, surface a
configuration error or require the user to provide a target server, while
preserving the existing servers[0].url() behavior when a server is configured.
- Line 31: Update the HTTP method resolution near the `method` constant to read
`method` from `operationBinding?.value()` first, then `channelBinding?.value()`,
before falling back to `'GET'` and applying `toUpperCase()`. Preserve the
existing precedence and default behavior while using the binding raw values
rather than nonexistent `Binding.method` properties.
- Around line 22-24: Update HttpExecutionComponent’s URL construction to resolve
server variables and channel parameters before calling fetch, using declared
defaults or collected values. Detect unresolved required placeholders in the
server URL or channel address and block execution instead of passing the
unresolved fullUrl to fetch; preserve normal execution once all values are
resolved.

In `@playground/components/plugins/WebhookPlugin.tsx`:
- Around line 20-22: Update the webhook execution flow around operation.messages
and firstMessage so users can select which available message to simulate, or
register a separate execution action for each message; ensure the selected
message’s payload schema is used instead of always choosing messages[0].
- Around line 27-40: Update the schema payload generator to detect example
fields by property existence rather than truthiness, preserving valid values
such as false, 0, and empty strings. Extend recursive generation beyond
primitive properties to support nested objects, arrays, numbers, enums, and
other valid JSON Schema constructs without defaulting supported values to null.

Prevent redundant plugin update renders.

Playground.render() creates a new plugin array on every render. AsyncApiStandalone.componentDidUpdate detects the new array identity and calls updatePlugins. Although plugin names prevent duplicate installation, updatePlugins always calls setState({}), causing an unnecessary additional render.

Keep the array stable at module scope:

Suggested stabilization
+const playgroundPlugins = [httpPlugin, webhookPlugin];

 // ...
-            <AsyncApi schema={schema} config={parsedConfig} plugins={[httpPlugin, webhookPlugin]} />
+            <AsyncApi schema={schema} config={parsedConfig} plugins={playgroundPlugins} />

Add cancellation and a request timeout.

executeRequest receives an already-started Promise<Response>, so it cannot attach an AbortSignal to either caller's fetch. A pending fetch or Response.text() call can leave loading true and the action disabled. Change the boundary to create each request with an AbortSignal, abort it after a bounded timeout, and abort it on component unmount.

Do not use the Playground origin when the operation has no server.

If servers is empty, this code sends the operation to an unrelated path on the Playground host. Show a configuration error or require the user to enter a target server.

Resolve server variables and channel parameters before calling fetch. HttpExecutionComponent is reachable through the playground and constructs fullUrl by joining the raw results of servers[0].url() and channel.address(). AsyncAPI definitions can contain {port} and {streetlightId} in those values. The current code preserves these placeholders and passes them to fetch, which can reject the URL or request the wrong endpoint. Use declared defaults or collected values, and block execution while required values remain unresolved.

@asyncapi/parser 3.6.3 HTTP binding method() source declaration

💡 Result:

In the @asyncapi/parser package (version 3.6.3), there is no method named method that directly handles HTTP binding source declarations [1][2]. The confusion likely stems from a combination of the AsyncAPI Specification's HTTP Binding Object and the AsyncAPI Parser API's structure [3][4][2]. 1. HTTP Binding 'method' Field: In the AsyncAPI specification, 'method' is a fixed field within the HTTP Operation Binding Object [3][4][5]. It is a string value (e.g., 'GET', 'POST') used to define the HTTP method for a specific operation within your AsyncAPI document [3][4]. It is not a code-level method of the parser [1][2]. 2. Accessing Bindings via Parser API: To access this binding information programmatically using the @asyncapi/parser, you use the Parser-API methods [6][2]. After parsing your AsyncAPI document, you typically navigate to the operation you are interested in and access its bindings [1][2]: - Use the operations method to retrieve the operations [1][2]. - Use the bindings method on a specific operation object to access its defined bindings [1][2]. - You can then use the get('http') method on the bindings collection to retrieve the HTTP-specific binding object, from which you can read the 'method' property [1][4][2]. The @asyncapi/parser provides helper functions to load documents from various sources (such as fromURL or fromFile), but these handle document retrieval and parsing, not the specific extraction of binding fields like 'method' [6][7].

site:github.com/asyncapi/parser-js HTTPBinding method property parser API

💡 Result:

There is no standard "HTTPBinding method property parser API." The term likely refers to the handling of protocol-specific bindings—specifically HTTP bindings—within the context of the AsyncAPI Parser-JS library [1][2]. In the AsyncAPI specification and its JavaScript parser (parser-js), "bindings" are used to define protocol-specific information (such as HTTP, Kafka, or AMQP) [3][4]. The parser provides methods to access these bindings as part of the document model [3][5]. Key technical points regarding this functionality include: 1. Binding Access: The parser includes a bindings() method within its document model (e.g., in v2/mixins.ts and v3/mixins.ts) that allows users to retrieve binding objects associated with channels, messages, or operations [3][6]. 2. HTTP Bindings: When an AsyncAPI document defines http bindings, they are processed by the parser and exposed through this bindings() API [3]. 3. Parsing Logic: The internal implementation of the bindings() method iterates over binding entries [3]. Recent updates to the parser have included fixes to ensure that keys such as $ref are filtered out during this process to prevent the parser from returning undefined or crashing when encountering referenced bindings [3]. 4. Parser-API Definition: The overall structure of the parser follows the AsyncAPI Parser-API, which defines the global methods available to developers, such as accessors for channels, messages, and bindings [1][5]. If you are encountering a specific error or trying to implement a parser for HTTP bindings, you should look at the bindings() method within the AsyncAPI parser-js library, which handles the extraction and normalization of these protocol-specific properties [3].

Read the HTTP method from the binding value

@asyncapi/parser 3.6.3 returns a generic Binding model. This model has no method property or method() accessor; its raw fields are returned by value(). The current expression therefore always falls back to 'GET', even when the binding specifies POST, PUT, or another method. Read operationBinding?.value()?.method and channelBinding?.value()?.method before calling toUpperCase().

method resolution near the `method` constant to read `method` from
`operationBinding?.value()` first, then `channelBinding?.value()`, before
falling back to `'GET'` and applying `toUpperCase()`. Preserve the existing
precedence and default behavior while using the binding raw values rather than
nonexistent `Binding.method` properties.

Include the operation payload for methods that require a body.

POST, PUT, and PATCH operations currently send an empty body. Operations with required message payloads will fail or execute with incorrect data.

Generate or accept a schema-based payload. Set the applicable Content-Type header.

Let the user select the webhook message.

An operation can contain multiple messages. This code always sends the first message and cannot simulate the other valid payloads.

Add a message selector or register one execution action for each message.

Generate a payload that conforms to the schema.

The generator converts nested objects, arrays, numbers, enums, and other valid property types to null. It also ignores falsy examples such as false, 0, and an empty string.

Use property-existence checks for examples. Generate values recursively for supported JSON Schema constructs.
