To use this module: The asynchronous form always takes a completion callback as its last argument. The arguments passed to the completion callback depend on the method, but the first argument is always reserved for an exception.

If the operation was completed successfully, then the first argument will be null or undefined. So the following is prone to error because the fs. The synchronous versions will block the entire process until they complete — halting all connections.

While it is not recommended, most fs functions allow the callback argument to be omitted, in which case a default callback is used that rethrows errors.

Omitting the callback function on asynchronous fs functions is deprecated and may result in an error being thrown in the future. String form paths are interpreted as UTF-8 character sequences identifying the absolute or relative filename.

Relative paths will be resolved relative to the current working directory as specified by process. On such systems, it is possible for a single file path to contain sub-sequences that use multiple character encodings.

As with string paths, Buffer paths may be relative or absolute: This behavior can be observed when using a drive path without a backslash. For more information, see this MSDN page.

URL object support Added in: Only URL objects using the file: URLs are always absolute paths. URLs with drive letters convert to local absolute paths. URLs without a hostname nor a drive letter will result in a throw: File URL path must be absolute file: URLs with drive letters must use: Using another separator will result in a throw.

On all other platforms, file: URLs with a hostname are unsupported and will result in a throw: URL having encoded slash characters will result in a throw on all platforms: URLs having encoded backslash will result in a throw: Each open file is assigned a simple numeric identifier called a file descriptor.

At the system-level, all file system operations use these file descriptors to identify and track each specific file.How to use node-docker-monitor module to monitor Docker containers and implement simple API Gateway for Dockerized microserivces.

This article describes the most straight forward approach. Another approach (using SkyDNS and Nginx as a reverse proxy) may offer better performance and scalability..

API Gateway and microservices. Microservice – is a software architecture pattern when a . Note: ECMAScript implementation in ph-vs.com and browsers is slightly different.

For example, {}+{} is '[object Object][object Object]' in ph-vs.com REPL, whereas the same code is NaN in the Chrome console because of the automatic semicolon insertion feature. An Agent is responsible for managing connection persistence and reuse for HTTP clients.

It maintains a queue of pending requests for a given host and port, reusing a single socket connection for each until the queue is empty, at which time the socket is either destroyed or put into a pool where it is kept to be used again for requests to the same host and port.

Under NTFS, if the filename contains a colon, ph-vs.com will open a file system stream, as described by this MSDN page. ph-vs.comr(path[, options]) # History. A stream is an abstract interface for working with streaming data in ph-vs.com The stream module provides a base API that makes it easy to build objects that implement the stream interface..

There are many stream objects provided by ph-vs.com For instance, a request to an HTTP server and ph-vs.com are both stream instances.
