Bun

指南執行時

使用 Bun 匯入 YAML 檔案

Bun 原生支援 .yaml.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檔案。

import config from "./config.yaml";

config.database.host; // => "localhost"
config.server.port; // => 3000
config.features.auth; // => true

您還可以使用具名匯入來解構頂層屬性

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 匯入屬性 語法

import config from "./config.yaml" with { type: "yaml" };

config.database.port; // => 5432

要在執行時解析 YAML 字串,請使用 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

要為您的 YAML 匯入新增 TypeScript 支援,請建立一個以 .d.ts 結尾的宣告檔案(例如,config.yamlconfig.yaml.d.ts);

config.yaml.d.ts
const contents: {
  database: {
    host: string;
    port: number;
    name: string;
  };
  server: {
    port: number;
    timeout: number;
  };
  features: {
    auth: boolean;
    rateLimit: boolean;
  };
};

export = contents;
