Install

dependencies:
  jala: ^0.8.2
  jala_http: ^0.8.2

Setup

import 'package:http/http.dart' as http;
import 'package:jala_http/jala_http.dart';

final client = JalaHttp.wrap(http.Client());
await client.get(Uri.parse('https://example.com'));

JalaHttp.wrap wraps the client (or a fresh one if omitted) and registers a JalaHttpReplayer for the inspector Replay action.

Capture only (no replay)

final client = JalaHttpClient(inner: http.Client());

Public API

API	Role
JalaHttp.wrap([client])	Wrap + register replayer
JalaHttpClient	Capture-only client
JalaHttpReplayer	Re-issue stored calls through the wrapped client

Behavior notes

Stream tee

send() returns a StreamedResponse. Jala tees the body: every chunk is forwarded to the app unmodified, while a separate buffer (capped at maxBodyBytes) holds an inspector preview. Large downloads are delivered in full to the app; only the preview truncates.

Replay

Rebuilds http.Request through the same wrapped client; new entry has replayOf. Masked headers / query params are not resent.

Last replayer wins if you also use JalaDio.attach — attach primary client last (ADOPTION.md).

Throttling

When a profile is active and the host matches:

• Drop → ClientException before the inner client
• Latency before forward
• Bandwidth in both directions (unlike Dio’s stream-only download pacing) — request and response streams are paced when configured

Production safety

• No-op when !isEnabled
• Capture never blocks or replaces the real request/response path
• Redaction + body caps — CONFIG.md
