CapacitorHttp

The Capacitor Http API provides native http support via patching fetch and XMLHttpRequest to use native libraries. It also provides helper methods for native http requests without the use of fetch and XMLHttpRequest. This plugin is bundled with @capacitor/core.

Configuration

By default, the patching of window.fetch and XMLHttpRequest to use native libraries is disabled. If you would like to enable this feature, modify the configuration below in the capacitor.config file.

Prop	Type	Description	Default
enabled	boolean	Enable the patching of fetch and XMLHttpRequest to use native libraries instead.	false

Example Configuration

In capacitor.config.json:

{
  "plugins": {
    "CapacitorHttp": {
      "enabled": true
    }
  }
}

In capacitor.config.ts:

import { CapacitorConfig } from '@capacitor/cli';

const config: CapacitorConfig = {
  plugins: {
    CapacitorHttp: {
      enabled: true,
    },
  },
};

export default config;

Example

import { CapacitorHttp } from '@capacitor/core';

// Example of a GET request
const doGet = () => {
  const options = {
    url: 'https://example.com/my/api',
    headers: { 'X-Fake-Header': 'Fake-Value' },
    params: { size: 'XL' },
  };

  const response: HttpResponse = await CapacitorHttp.get(options);

  // or...
  // const response = await CapacitorHttp.request({ ...options, method: 'GET' })
};

// Example of a POST request. Note: data
// can be passed as a raw JS Object (must be JSON serializable)
const doPost = () => {
  const options = {
    url: 'https://example.com/my/api',
    headers: { 'X-Fake-Header': 'Fake-Value' },
    data: { foo: 'bar' },
  };

  const response: HttpResponse = await CapacitorHttp.post(options);

  // or...
  // const response = await CapacitorHttp.request({ ...options, method: 'POST' })
};

Large File Support

Due to the nature of the bridge, parsing and transferring large amount of data from native to the web can cause issues. Support for downloading and uploading files has been added to the @capacitor/file-transfer plugin. In many cases, you may also need @capacitor/filesystem to generate a valid file URI.

Blob

A file-like object of immutable, raw data. Blobs represent data that isn't necessarily in a JavaScript-native format. The File interface is based on Blob, inheriting blob functionality and expanding it to support files on the user's system.

Represents a raw buffer of binary data, which is used to store data for the different typed arrays. ArrayBuffers cannot be read from or written to directly, but can be passed to a typed array or DataView Object to interpret the raw buffer as needed.

Prop	Type	Description
byteLength	number	Read-only. The length of the ArrayBuffer (in bytes).

Method	Signature	Description
slice	(begin: number, end?: number) => ArrayBuffer	Returns a section of an ArrayBuffer.

ReadableStream

This Streams API interface represents a readable stream of byte data. The Fetch API offers a concrete instance of a ReadableStream through the body property of a Response object.

value

ReadableWritablePair

Prop	Type	Description
readable	ReadableStream<R>
writable	WritableStream<W>	Provides a convenient, chainable way of piping this readable stream through a transform stream (or any other { writable, readable } pair). It simply pipes the stream into the writable side of the supplied pair, and returns the readable side for further use. Piping a stream will lock it for the duration of the pipe, preventing any other consumer from acquiring a reader.

WritableStream

This Streams API interface provides a standard abstraction for writing streaming data to a destination, known as a sink. This object comes with built-in backpressure and queuing.

Prop	Type
locked	boolean

Method	Signature
abort	(reason?: any) => Promise<void>
getWriter	() => WritableStreamDefaultWriter<W>

WritableStreamDefaultWriter

This Streams API interface is the object returned by WritableStream.getWriter() and once created locks the < writer to the WritableStream ensuring that no other streams can write to the underlying sink.

Prop	Type
closed	Promise<undefined>
desiredSize	number
ready	Promise<undefined>

Method	Signature
abort	(reason?: any) => Promise<void>
close	() => Promise<void>
releaseLock	() => void
write	(chunk: W) => Promise<void>

StreamPipeOptions

Prop	Type	Description
preventAbort	boolean
preventCancel	boolean
preventClose	boolean	Pipes this readable stream to a given writable stream destination. The way in which the piping process behaves under various error conditions can be customized with a number of passed options. It returns a promise that fulfills when the piping process completes successfully, or rejects if any errors were encountered. Piping a stream will lock it for the duration of the pipe, preventing any other consumer from acquiring a reader. Errors and closures of the source and destination streams propagate as follows: An error in this source readable stream will abort destination, unless preventAbort is truthy. The returned promise will be rejected with the source's error, or with any error that occurs during aborting the destination. An error in destination will cancel this source readable stream, unless preventCancel is truthy. The returned promise will be rejected with the destination's error, or with any error that occurs during canceling the source. When this source readable stream closes, destination will be closed, unless preventClose is truthy. The returned promise will be fulfilled once this process completes, unless an error is encountered while closing the destination, in which case it will be rejected with that error. If destination starts out closed or closing, this source readable stream will be canceled, unless preventCancel is true. The returned promise will be rejected with an error indicating piping to a closed stream failed, or with any error that occurs during canceling the source. The signal option can be set to an AbortSignal to allow aborting an ongoing pipe operation via the corresponding AbortController. In this case, this source readable stream will be canceled, and destination aborted, unless the respective options preventCancel or preventAbort are set.
signal	AbortSignal

AbortSignal

A signal object that allows you to communicate with a DOM request (such as a Fetch) and abort it if required via an AbortController object.

Prop	Type	Description
aborted	boolean	Returns true if this AbortSignal's AbortController has signaled to abort, and false otherwise.
onabort	(this: AbortSignal, ev: Event) => any

Method	Signature	Description
addEventListener	<K extends "abort">(type: K, listener: (this: AbortSignal, ev: AbortSignalEventMap[K]) => any, options?: boolean | AddEventListenerOptions) => void	Appends an event listener for events whose type attribute value is type. The callback argument sets the callback that will be invoked when the event is dispatched. The options argument sets listener-specific options. For compatibility this can be a boolean, in which case the method behaves exactly as if the value was specified as options's capture. When set to true, options's capture prevents callback from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE. When false (or not present), callback will not be invoked when event's eventPhase attribute value is CAPTURING_PHASE. Either way, callback will be invoked if event's eventPhase attribute value is AT_TARGET. When set to true, options's passive indicates that the callback will not cancel the event by invoking preventDefault(). This is used to enable performance optimizations described in § 2.8 Observing event listeners. When set to true, options's once indicates that the callback will only be invoked once after which the event listener will be removed. The event listener is appended to target's event listener list and is not appended if it has the same type, callback, and capture.
addEventListener	(type: string, listener: EventListenerOrEventListenerObject, options?: boolean | AddEventListenerOptions) => void	Appends an event listener for events whose type attribute value is type. The callback argument sets the callback that will be invoked when the event is dispatched. The options argument sets listener-specific options. For compatibility this can be a boolean, in which case the method behaves exactly as if the value was specified as options's capture. When set to true, options's capture prevents callback from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE. When false (or not present), callback will not be invoked when event's eventPhase attribute value is CAPTURING_PHASE.

This is used to enable performance optimizations described in § 2.8 Observing event listeners. When set to true, options's once indicates that the callback will only be invoked once after which the event listener will be removed. The event listener is appended to target's event listener list and is not appended if it has the same type, callback, and capture.
removeEventListener	<K extends "abort">(type: K, listener: (this: AbortSignal, ev: AbortSignalEventMap[K]) => any, options?: boolean | EventListenerOptions) => void	Removes the event listener in target's event listener list with the same type, callback, and options.
removeEventListener	(type: string, listener: EventListenerOrEventListenerObject, options?: boolean | EventListenerOptions) => void	Removes the event listener in target's event listener list with the same type, callback, and options.

Method	Signature	Description
composedPath	() => EventTarget[]	Returns the invocation target objects of event's path (objects on which listeners will be invoked), except for any nodes in shadow trees of which the shadow root's mode is "closed" that are not reachable from event's currentTarget.
initEvent	(type: string, bubbles?: boolean, cancelable?: boolean) => void
preventDefault	() => void	If invoked when the cancelable attribute value is true, and while executing a listener for the event with passive set to false, signals to the operation that caused event to be dispatched that it needs to be canceled.
stopImmediatePropagation	() => void	Invoking this method prevents event from reaching any registered event listeners after the current one finishes running and, when dispatched in a tree, also prevents event from reaching any other objects.
stopPropagation	() => void	When dispatched in a tree, invoking this method prevents event from reaching any objects other than the current object.

When set to true, options's once indicates that the callback will only be invoked once after which the event listener will be removed. The event listener is appended to target's event listener list and is not appended if it has the same type, callback, and capture.
dispatchEvent	(event: Event) => boolean	Dispatches a synthetic event event to target and returns true if either event's cancelable attribute value is false or its preventDefault() method was not invoked, and false otherwise.
removeEventListener	(type: string, callback: EventListenerOrEventListenerObject | null, options?: EventListenerOptions | boolean) => void	Removes the event listener in target's event listener list with the same type, callback, and options.
