匯入 YAML 檔案
Bun 原生支援 .yaml 和 .yml 匯入。
config.yaml
database:
host: localhost
port: 5432
name: myapp
server:
port: 3000
timeout: 30
features:
auth: true
rateLimit: true
像匯入其他原始檔一樣匯入該檔案。
import config from "./config.yaml";
config.database.host; // => "localhost"
config.server.port; // => 3000
config.features.auth; // => true
你也可以通過命名匯入解構頂層屬性:
import { database, server, features } from "./config.yaml";
console.log(database.name); // => "myapp"
console.log(server.timeout); // => 30
console.log(features.rateLimit); // => true
Bun 還支援 Import Attributes 語法:
import config from "./config.yaml" with { type: "yaml" };
config.database.port; // => 5432
要在執行環境解析 YAML 字串,可以使用 Bun.YAML.parse():
const yamlString = `
name: John Doe
age: 30
hobbies:
- reading
- coding
`;
const data = Bun.YAML.parse(yamlString);
console.log(data.name); // => "John Doe"
console.log(data.hobbies); // => ["reading", "coding"]
TypeScript 支援
要為 YAML 匯入新增 TypeScript 支援,請建立一個在 YAML 檔名後附加 .d.ts 的宣告檔案(例如,config.yaml → config.yaml.d.ts):
declare const contents: {
database: {
host: string;
port: number;
name: string;
};
server: {
port: number;
timeout: number;
};
features: {
auth: boolean;
rateLimit: boolean;
};
};
export = contents;
