{@link encode} and {@link decode} for base64 encoding.

The base class that all derivative HTTP extend, providing a status and an expose property.

A cryptographic key chain which allows signing of data to prevent tampering, but also allows for easy key rotation without needing to re-sign the data.

Provides an way to manage cookies in a request and response on the server as a single iterable collection, as well as the ability to sign and verify cookies to prevent tampering.

An event which contains information which will be sent to the remote connection and be made available in an EventSource as an event. A server creates new events and dispatches them on the target which will then be sent to a client.

An implementation of ServerSentEventTarget that provides a readable stream as a body of a response to establish a connection to a client.

Standard HTTP status codes.

A namespace that contains each error constructor. Each error extends HTTPError and provides .status and .expose properties, where the .status will be an error Status value and .expose indicates if information, like a stack trace, should be shared in the response.

A record of all the status codes text.

Returns an array of media types accepted by the request, in order of preference. If there are no media types supplied in the request, then any media type selector will be returned.

Returns an array of content encodings accepted by the request, in order of preference. If there are no encoding supplied in the request, then ["*"] is returned, implying any encoding is accepted.

Returns an array of languages accepted by the request, in order of preference. If there are no languages supplied in the request, then ["*"] is returned, imply any language is accepted.

Decodes a given RFC4648 base64 encoded string

CREDIT: https://gist.github.com/enepomnyaschih/72c423f727d395eeaa09697058238727 Encodes a given Uint8Array, ArrayBuffer or string into RFC4648 base64 representation

Calculate an ETag for an entity. When the entity is a specific set of data it will be fingerprinted as a "strong" tag, otherwise if it is just file information, it will be calculated as a weak tag.

Compile a string to a template function for the path.

Concatenate the given arrays into a new Uint8Array.

Given an extension or media type, return a full Content-Type or Content-Disposition header value.

Copy bytes from the src array to the dst array. Returns the number of bytes copied.

A factory function which provides a way to create errors. It takes up to 3 arguments, the error Status, an message, which defaults to the status text and error options, which incudes the expose property to set the .expose value on the error.

Creates a Promise with the reject and resolve functions placed as methods on the promise object itself.

Check whether binary arrays are equal to each other.

For a given media type, return the most relevant extension, or undefined if no extension can be found.

A helper function that takes the value from the If-Match header and a calculated etag for the target. By using strong comparison, return true if the values match, otherwise false.

A helper function that takes the value from the If-None-Match header and a calculated etag for the target entity and returns false if the etag for the entity matches the supplied value, otherwise true.

A type guard that determines if the value is an HttpError or not.

Allows merging of various sources of headers into a final set of headers which can be used in a {@link Response}.

Create path match function from path-to-regexp spec.

Parse a string for the raw tokens.

Normalize the given path string, returning a regular expression.

Read Reader r until EOF (null) and resolve to the content as Uint8Array`.

Create a Reader from a ReadableStreamDefaultReader.

Compare to array buffers or data views in a way that timing based attacks cannot gain information about the platform.

Returns the media type associated with the file extension. Values are normalized to lower case and matched irrespective of a leading ..

Write all the content of the array buffer (arr) to the writer (w).

Just the part of Deno.FileInfo that is required to calculate an ETag, so partial or user generated file information can be passed.

Metadata about a key.
