Declarative configuration microframework for Mesh IoC.

Highlights

• 🗜 Tidy and compact
• 💻 Works in browser
• 🔬 Strongly typed and introspectable
• 🌳 Ergonomic

Usage

1. Define and use configs in your classes:

export class MyDatabase {
    @config() DATABASE_USERNAME!: string;
    @config() DATABASE_PASSWORD!: string;
    @config({ default: 10 }) DATABASE_MAX_CONNECTIONS!: number;

    async connect() {
        await this.db.connect({
            username: this.DATABASE_USERNAME,
            password: this.DATABASE_PASSWORD,
            maxConnections: this.DATABASE_MAX_CONNECTIONS,
        });
    }
}

2. Define Config provider in Mesh:

mesh.service(MyDatabase);
mesh.service(Config, ProcessEnvConfig);

3. Now DATABASE_* values will be read from process.env.

4. Enjoy!
