http2 createserver options onrequesthandler

• options {Object}
  • maxDeflateDynamicTableSize {number} Sets the maximum dynamic table size for deflating header fields. Default: 4Kib.
  • maxSettings {number} Sets the maximum number of settings entries per SETTINGS frame. The minimum value allowed is 1. Default: 32.
  • maxSessionMemory{number} Sets the maximum memory that the Http2Session is permitted to use. The value is expressed in terms of number of megabytes, e.g. 1 equal 1 megabyte. The minimum value allowed is 1. This is a credit based limit, existing Http2Streams may cause this limit to be exceeded, but new Http2Stream instances will be rejected while this limit is exceeded. The current number of Http2Stream sessions, the current memory use of the header compression tables, current data queued to be sent, and unacknowledged PING and SETTINGS frames are all counted towards the current limit. Default: 10.
  • maxHeaderListPairs {number} Sets the maximum number of header entries. This is similar to [http.Server#maxHeadersCount][] or [http.ClientRequest#maxHeadersCount][]. The minimum value is 4. Default: 128.
  • maxOutstandingPings {number} Sets the maximum number of outstanding, unacknowledged pings. Default: 10.
  • maxSendHeaderBlockLength {number} Sets the maximum allowed size for a serialized, compressed block of headers. Attempts to send headers that exceed this limit will result in a 'frameError' event being emitted and the stream being closed and destroyed.
  • paddingStrategy {number} The strategy used for determining the amount of padding to use for HEADERS and DATA frames. Default: http2.constants.PADDING_STRATEGY_NONE. Value may be one of:
    • http2.constants.PADDING_STRATEGY_NONE: No padding is applied.
    • http2.constants.PADDING_STRATEGY_MAX: The maximum amount of padding, determined by the internal implementation, is applied.
    • http2.constants.PADDING_STRATEGY_ALIGNED: Attempts to apply enough padding to ensure that the total frame length, including the 9-byte header, is a multiple of 8. For each frame, there is a maximum allowed number of padding bytes that is determined by current flow control state and settings. If this maximum is less than the calculated amount needed to ensure alignment, the maximum is used and the total frame length is not necessarily aligned at 8 bytes.
  • peerMaxConcurrentStreams {number} Sets the maximum number of concurrent streams for the remote peer as if a SETTINGS frame had been received. Will be overridden if the remote peer sets its own value for maxConcurrentStreams. Default: 100.
  • maxSessionInvalidFrames {integer} Sets the maximum number of invalid frames that will be tolerated before the session is closed. Default: 1000.
  • maxSessionRejectedStreams {integer} Sets the maximum number of rejected upon creation streams that will be tolerated before the session is closed. Each rejection is associated with an NGHTTP2_ENHANCE_YOUR_CALM error that should tell the peer to not open any more streams, continuing to open streams is therefore regarded as a sign of a misbehaving peer. Default: 100.
  • settings {HTTP/2 Settings Object} The initial settings to send to the remote peer upon connection.
  • Http1IncomingMessage {http.IncomingMessage} Specifies the IncomingMessage class to used for HTTP/1 fallback. Useful for extending the original http.IncomingMessage. Default: http.IncomingMessage.
  • Http1ServerResponse {http.ServerResponse} Specifies the ServerResponse class to used for HTTP/1 fallback. Useful for extending the original http.ServerResponse. Default: http.ServerResponse.
  • Http2ServerRequest {http2.Http2ServerRequest} Specifies the Http2ServerRequest class to use. Useful for extending the original Http2ServerRequest. Default: Http2ServerRequest.
  • Http2ServerResponse {http2.Http2ServerResponse} Specifies the Http2ServerResponse class to use. Useful for extending the original Http2ServerResponse. Default: Http2ServerResponse.
  • …: Any [net.createServer()][] option can be provided.
• onRequestHandler {Function} See [Compatibility API][]
• Returns: {Http2Server}

Returns a net.Server instance that creates and manages Http2Session instances.

Since there are no browsers known that support [unencrypted HTTP/2][HTTP/2 Unencrypted], the use of [http2.createSecureServer()][] is necessary when communicating with browser clients.

const http2 = require('http2');
// Create an unencrypted HTTP/2 server.
// Since there are no browsers known that support

const server = http2.createServer();
