TypeScript factories for generating fixtures, with custom constructor support. No docs yet, sorry.

class ClassFactory {
    constructor(clazz, constructorParameterFn, attributeCreatorFn) {
        this.parseFnOrValue = (val, fallbackValue) => {
            if (typeof val === "function") {
                return val();
            }
            return (val !== null && val !== void 0 ? val : (fallbackValue ? this.parseFnOrValue(fallbackValue) : undefined));
        };
        this.generate = (attributeOverrides) => {
            let newInstance = new this.clazz(...this.parseFnOrValue(this.constructorParams, []));
            return Object.assign(newInstance, this.parseFnOrValue(this.extraAttributes, {}), this.parseFnOrValue(attributeOverrides, {}));
        };
        this.generateMany = (howMany, attributeOverrides) => {
            const arr = Array(howMany).fill(undefined);
            return arr.map(() => this.generate(attributeOverrides));
        };
        this.extend = (options) => {
            const { constructorParams, extraAttributes } = options;
            return new ClassFactory(this.clazz, () => this.parseFnOrValue(constructorParams, this.constructorParams), () => Object.assign(this.parseFnOrValue(this.extraAttributes, {}), this.parseFnOrValue(extraAttributes, {})));
        };
        this.extraAttributes = attributeCreatorFn;
        this.constructorParams = constructorParameterFn;
        this.clazz = clazz;
    }
}

export { ClassFactory };
