Node.js 的原生抽象


本文档中说明的每个示例都直接使用 Node.js 和 V8 API 来实现插件。 从一个 V8 版本到下一个版本(以及一个主要的 Node.js 版本到下一个版本),V8 API 可能并且已经发生了巨大的变化。 每次更改时,插件可能需要更新和重新编译才能继续运行。 Node.js 发布计划旨在最小化此类更改的频率和影响,但 Node.js 几乎无法确保 V8 API 的稳定性。

Each of the examples illustrated in this document directly use the Node.js and V8 APIs for implementing addons. The V8 API can, and has, changed dramatically from one V8 release to the next (and one major Node.js release to the next). With each change, addons may need to be updated and recompiled in order to continue functioning. The Node.js release schedule is designed to minimize the frequency and impact of such changes but there is little that Node.js can do to ensure stability of the V8 APIs.

The Native Abstractions for Node.js (or nan) provide a set of tools that addon developers are recommended to use to keep compatibility between past and future releases of V8 and Node.js. See the nan examples for an illustration of how it can be used.
