$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
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.

在
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
. Inprod
, this behavior will depend on your adapter.
