A MetaClass that helps you to generate some JavaScript Class definitions.

Why

I wanted to recreate Google App Script API with this repo without needing to look into GAS documentation. More information, visit the repo and check out (:

Usage

Your simple code

  const myMetaClass = new MetaClass('User', {
    properties: [
      new Propertie('name', { type: 'String' }),
      new Propertie('age', { type: 'Integer', default: 20, lookUps: true }),
    ],
    functions: [
      new Function('isUserUnderAge', { type: 'Boolean' }),
      new Function('toString', { type: 'String' }),
      new Function('createUser', { type: 'User', static: true, parameters: [ new Propertie('user', { type: 'User' }) ] } ),
      new Function('addRole', { parameters: [ new Propertie('role', { type: 'Role' }) ] } )
    ]
  });
  
  console.log(myMetaClass.build());

Results:

  import Role from 'Role';
  
  class User {
    name: string;
    age: integer = 20;
    
    /* Class actions */
    static createUser(user: User ): User {
      // TODO implement
    }
    
    /* Instance actions */
    addRole(role:  Role) {
      // TODO implement
    }
    
    toString(): string {
      // TODO implement
    }

    /* Look ups */
    get age() {
      // TODO implement
    }
    
    set age() {
      // TODO implement
    }
  }
  
  exports default User;
