MetaForge V0.8.0

Update 2023-11-08

JSDOC

To have JSDOC comments in your type annotations you need to add $meta field to your
schema; Also, your $meta properties should start with @;

Example

({
  reciever: 'number',
  money: 'number',
  $meta: {
    '@version': 'v1',
    '@name': 'Pay check',
    '@description': 'Cash settlement',
    '@example': '<caption>Check example</caption>\n{ money: 100, reciever: 2 }',
  },
});

Calculated fields

Calculated fields supposed to do preprocessing of your schema;

Warning: experimental. We do not support some types yet: Map, Set

Example

const schema = {
  $id: 'user',
  name: 'string',
  phrase: (sample, schema, root) => 'Hello ' + schema.name + ' !',
};
const sample = { name: 'Alexander' };
new Schema(schema).calc(sample); // { ..., name: 'Alexander', phrase: 'Hello Alexander !'};
schema; // { $id: 'user', name: 'Alexander', phrase: 'Hello Alexander !'};

Writing calculated fields

Calculated fields is a function that receives two arguments:

• root: root object { input: Sample }
• parent: assigned target object

Warning: your return value will be assigned to samples

Additional

Method schema.calc receives mode as second parameter; This method allow to specify
return value as:

• Schema.calc(sample, true); // Returns copy of sample with assigned values
• Schema.calc(sample); // Returns sample object with assigned values

MetaForge V0.6.0

Update 2023-11-06

• Typescript generation module
• Documentation fixes

MetaForge V0.5.0

Update 2023-11-05

• Readme enhancement
• JSDOC documentation

MetaForge V0.4.0

Update 2023-11-05

• Support latest:21 node version

• Removed parser (maybe temporary)

• TypeScript .d.ts support

• Schema field with multiple type variants now works only with special type union

• Modular mechanism (internal rework): How it works

  const schema = new Schema();
  schema.register((schema, options, plan) => {}); //? Register new module

  By default registrated modules are:

  • Metatest module (Adds tests for prototypes)
  • Metatype module (Typescript parser)
  • Handyman (Quality of life module)

  But you also remove default modules:

  Schema.modules.delete('metatest');

• New shorthands for:

  • enum example: ['winter', 'spring', 'summer, 'autumn']
  • tuple example: ['string', 'number']
  • object example: { a: string, b: number }
  • string example: 'string'
  • schema example: 'MyGlobalSchema'
  • schema#2 example: new Schema('string')

• Removed preprocessor mechanism

• Schemas now can be part of plan

• Performance improvements (by removing unnecessary modules)

• Lightweight inheritance

• Removed type JSON (temporary)

• Prototype chaining

• Partial testing

• New prototypes:

  • Tuple
  • Record
  • Schema
  • Union

MetaForge V0.3.0

Release 2023-10-16

• Schema child method, now you can update only schema or only options for new schemas
• Metadata fetcher, now you can gather all metadata by schema.meta
• Fixed case when schema returns only methods without metadata, now it returns prototypes key with
  all metadata
• Preprocess & postprocess for objects properties mutations
• New prototype enum
• Code cleanup & tests
