A lightweight TypeScript library for basic storage management.
npm install @typescript-package/data --save-peernpm install @typescript-package/storage --save-peerimport {
IndexedWeakStorage,
WeakStorage,
} from '@typescript-package/storage';The IndexedWeakStorage class is a concrete class that manages IndexedWeakStorage instance in a static Map where data is associated with a specified name in the WeakMap and index provided by the given key.
import { IndexedWeakStorage } from '@typescript-package/storage';
export interface Profile {
id: number,
age: number;
score: number;
firstName: string;
lastName: string;
};
new IndexedWeakStorage(
{ id: 1, firstName: 'first', lastName: 'last', age: 27, score: 1100 } as Profile,
'id',
'profiles1'
);
new IndexedWeakStorage(
{ id: 1, firstName: 'first1', lastName: 'last1', age: 127, score: 1200 } as Profile,
'id',
'profiles2'
);
console.log(
`IndexedWeakStorage.getByIndex(1, 'profiles2'): `,
IndexedWeakStorage.getByIndex(1, 'profiles2') // { id: 1, firstName: 'first1', lastName: 'last1', age: 127, score: 1200 }
);The WeakStorage class is a concrete class that manages WeakStorage instance in a static Map where data is associated with a specified name in the WeakMap.
import { WeakStorage } from '@typescript-package/storage';
// Define a class that extends WeakStorage
export class ProfileData extends WeakStorage<number, 'age' | 'score'> {}
// Create two instances with different names
const ageData = new ProfileData(25, 'age');
const scoreData = new ProfileData(90, 'score');
// Access the values stored in each instance using their respective names
console.log(ageData.value); // Outputs: 25
console.log(scoreData.value); // Outputs: 90
// You can also retrieve the data from another instance using the static method `getFrom`
console.log(WeakStorage.get('age', ageData)); // Outputs: 25
console.log(WeakStorage.get('score', scoreData)); // Outputs: 90
// Setting new values
ageData.set(30);
console.log(ageData.value); // Outputs: 30
// Destroy an instance and clear its stored data
ageData.destroy();
console.log(WeakStorage.get('age', ageData)); // Outputs: undefined
// Clear all stored values from the map
scoreData.delete();
console.log(WeakStorage.get('score', scoreData)); // Outputs: undefinedYour contributions are valued! If you'd like to contribute, please feel free to submit a pull request. Help is always appreciated.

Given a version number MAJOR.MINOR.PATCH, increment the:
- MAJOR version when you make incompatible API changes,
- MINOR version when you add functionality in a backwards-compatible manner, and
- PATCH version when you make backwards-compatible bug fixes.
Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.
FAQ How should I deal with revisions in the 0.y.z initial development phase?
The simplest thing to do is start your initial development release at 0.1.0 and then increment the minor version for each subsequent release.
How do I know when to release 1.0.0?
If your software is being used in production, it should probably already be 1.0.0. If you have a stable API on which users have come to depend, you should be 1.0.0. If you’re worrying a lot about backwards compatibility, you should probably already be 1.0.0.
