Nest is a framework for building efficient, scalable Node.js server-side applications. It uses progressive JavaScript, is built with TypeScript and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional R

Instead, it will be established before the first microservice call, and then reused across each subsequent call. However, if you want to delay the application bootstrapping process until a connection is established, you can manually initiate a connection using the ClientProxy object's connect() ...
These nests are hypothesized to have a protective function against predators. However, predators are not the only natural enemies, pathogens are also important. If the nest has a protective effect against microbes, and if waste management plays a role in nest sanitation, it is expected that the...
make changes to the request and the response objects. end the request-response cycle. call the next middleware function in the stack. if the current middleware function does not end the request-response cycle, it must call next() to pass control to the next middleware function. Otherwise, the...
Nest.js introduces a modern way of building Node.js apps by giving it a proper and modular structure out of the box. It was fully built with TypeScript but still preserves compatibility with plain JavaScript. Nest.js通过提供一种现成的,适当的模块化结构,引入了一种构建Node.js应用程序的现代方法...
