$env/dynamic/private

此模块提供对运行时环境变量的访问,这些变量由你正在运行的平台定义。例如,如果你正在使用 adapter-node(或运行 vite preview),这相当于 process.env。此模块仅包含不以 config.kit.env.publicPrefix 开头且以 config.kit.env.privatePrefix 开头的变量(如果已配置)。

¥This module provides access to runtime environment variables, as defined by the platform you’re running on. For example if you’re using adapter-node (or running vite preview), this is equivalent to process.env. This module only includes variables that do not begin with config.kit.env.publicPrefix and do start with config.kit.env.privatePrefix (if configured).

此模块无法导入客户端代码。

¥This module cannot be imported into client-side code.

预渲染期间不能使用动态环境变量。

¥Dynamic environment variables cannot be used during prerendering.

var console: Console

The console module provides a simple debugging console that is similar to the JavaScript console mechanism provided by web browsers.

The module exports two specific components:

  • A Console class with methods such as console.log(), console.error() and console.warn() that can be used to write to any Node.js stream.
  • A global console instance configured to write to process.stdout and process.stderr. The global console can be used without calling require('console').

Warning: The global console object’s methods are neither consistently synchronous like the browser APIs they resemble, nor are they consistently asynchronous like all other Node.js streams. See the note on process I/O for more information.

Example using the global console:

console.log('hello world');
// Prints: hello world, to stdout
console.log('hello %s', 'world');
// Prints: hello world, to stdout
console.error(new Error('Whoops, something bad happened'));
// Prints error message and stack trace to stderr:
//   Error: Whoops, something bad happened
//     at [eval]:5:15
//     at Script.runInThisContext (node:vm:132:18)
//     at Object.runInThisContext (node:vm:309:38)
//     at node:internal/process/execution:77:19
//     at [eval]-wrapper:6:22
//     at evalScript (node:internal/process/execution:76:60)
//     at node:internal/main/eval_string:23:3

const name = 'Will Robinson';
console.warn(`Danger ${name}! Danger!`);
// Prints: Danger Will Robinson! Danger!, to stderr

Example using the Console class:

const out = getStreamSomehow();
const err = getStreamSomehow();
const myConsole = new console.Console(out, err);

myConsole.log('hello world');
// Prints: hello world, to out
myConsole.log('hello %s', 'world');
// Prints: hello world, to out
myConsole.error(new Error('Whoops, something bad happened'));
// Prints: [Error: Whoops, something bad happened], to err

const name = 'Will Robinson';
myConsole.warn(`Danger ${name}! Danger!`);
// Prints: Danger Will Robinson! Danger!, to err
@seesource
console
.Console.log(message?: any, ...optionalParams: any[]): void (+1 overload)

Prints to stdout with newline. Multiple arguments can be passed, with the first used as the primary message and all additional used as substitution values similar to printf(3) (the arguments are all passed to util.format()).

const count = 5;
console.log('count: %d', count);
// Prints: count: 5, to stdout
console.log('count:', count);
// Prints: count: 5, to stdout

See util.format() for more information.

dev 中,$env/dynamic 始终包含来自 .env 的环境变量。在 prod 中,此行为取决于你的适配器。

¥In dev, $env/dynamic always includes environment variables from .env. In prod, this behavior will depend on your adapter.
