$env/dynamic/private
このモジュールは実行中の環境変数へのアクセスを提供します。変数は、実行しているプラットフォームによって定義されます。たとえば、adapter-node
を使用している場合(または vite preview
を実行している場合)、これは process.env
と同等になります。このモジュールには、config.kit.env.publicPrefix
で始まらず、config.kit.env.privatePrefix
で始まる(設定されている場合)変数のみが含まれます。
このモジュールはクライアント側のコードにインポートできません。
動的環境変数は、プリレンダリング中は使用できません。
import { import env
env } from '$env/dynamic/private';
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 ${name}! Danger!`);
// Prints: Danger Will Robinson! Danger!, to err
console.Console.log(message?: any, ...optionalParams: any[]): void (+1 overload)
Prints to stdout
with newline. Multiple arguments can be passed, with the
first used as the primary message and all additional used as substitution
values similar to printf(3)
(the arguments are all passed to util.format()
).
const count = 5;
console.log('count: %d', count);
// Prints: count: 5, to stdout
console.log('count:', count);
// Prints: count: 5, to stdout
See util.format()
for more information.
log(import env
env.DEPLOYMENT_SPECIFIC_VARIABLE);
dev
では、$env/dynamic
には常に.env
の環境変数が含まれます。prod
では、この動作はアダプターによって異なります。
