jarle Import a JSON5 file
Bun natively supports .json5 imports.
{
// Comments are allowed
database: {
host: "localhost",
port: 5432,
name: "myapp",
},
server: {
port: 3000,
timeout: 30,
},
features: {
auth: true,
rateLimit: true,
},
}
Import the file like any other source file.
import config from "./config.json5";
config.database.host; // => "localhost"
config.server.port; // => 3000
config.features.auth; // => true
You can also use named imports to destructure top-level properties:
import { database, server, features } from "./config.json5";
console.log(database.name); // => "myapp"
console.log(server.timeout); // => 30
console.log(features.rateLimit); // => true
For parsing JSON5 strings at runtime, use Bun.JSON5.parse():
const data = JSON5.parse(`{
name: 'John Doe',
age: 30,
hobbies: [
'reading',
'coding',
],
}`);
console.log(data.name); // => "John Doe"
console.log(data.hobbies); // => ["reading", "coding"]
