在微信小程序中直接运行React组件

在研究跨端开发时,我的一个重要目标,是可以让react组件跑在微信小程序中。在这个过程中,我探索了微信小程序的架构,并且引发了很多思考。而作为跨端开发,实际上很难做到 write once,run anywhere,因为每个平台所提供的能力是不一样的,例如微信小程序提供了原生的能力,例如调起摄像头或其他需要原生环境支持的能力,在微信小程序中开发虽然也是在webview中开展,但是,却需要一些原生的思维。所以,要做到 write once 就必须有一些限制,这些限制注定了我们无法完全利用小程序的能力,仅仅只用到一些布局的能力而已。所以,奉劝各位,在做跨端开发时,要有个心理准备。但如果跳出跨端开发,我现在只开发小程序,那我能否用我熟悉的react来开发呢?甚至,能否用我开发的nautil框架来开发呢?答案是可以的,本文将带你一步一步实现自己的react小程序开发之路,帮助你在某些特定的场景下,完成react项目往小程序迁移的目标。

React极简教程: Hello,World!React简史React安装Hello,World

A programming paradigm is a fundamental style of computer programming. There are four main paradigms: imperative, declarative, functional (which is considered a subset of the declarative paradigm) and object-oriented. Declarative programming : is a programming paradigm that expresses the logic of a computation(What do) without describing its control flow(How do). Some well-known examples of declarative domain specific languages (DSLs) include CSS, regular expressions, and a subset of SQL (SELECT queries, for example) Many markup languages such as HTML, MXML, XAML, XSLT… are often declarative. The declarative programming try to blur the distinction between a program as a set of instructions and a program as an assertion about the desired answer. Imperative programming : is a programming paradigm that describes computation in terms of statements that change a program state. The declarative programs can be dually viewed as programming commands or mathematical assertions. Functional programming : is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data. It emphasizes the application of functions, in contrast to the imperative programming style, which emphasizes changes in state. In a pure functional language, such as Haskell, all functions are without side effects, and state changes are only represented as functions that transform the state. ( 出处:维基百科)
