load-as-mixin

This is part of the ES-Git project.

Install

npm install --save @es-git/load-as-mixin

Usage

Mix this in with an IObjectRepo.

This mixin makes it easier to load objects from the repo. Each method takes a hash and attempts to load the object with that hash. If the object does not exist or is not of the type exected, an Error is thrown.

import objectsMixin from '@es-git/objects-mixin';
import loadAsMixin from '@es-git/load-as-mixin';
import MemoryRepo from '@es-git/memory-repo';

const Repo = mix(MemoryRepo)
            .with(objectsMixin)
            .with(loadAsMixin);

const repo = new Repo();
const text = await repo.loadText(hash);
const tree = await repo.loadTree(hash);
