如何在流星中使用带有打字稿的mongo模式验证？

Question

在使用 Typescript 时，Meteor 1.3 中是否有使用模式验证的包。 Meteor 指南中推荐的包（aldeed:simple-schema）似乎没有定义文件。

那么改用什么，或者 Typescript 有一个内置的方法可以做到这一点？

Answer 1

用于 Meteor 1.3 及更高版本的 Typescript 的最佳包是 aldeed:node-simple-schema。

来自文档：

SimpleSchema 的历史

SimpleSchema 于 2013 年年中首次作为 Meteor 包发布。 1.0 版于 2014 年 9 月发布。2016 年年中，2.0 版 以 NPM 包的形式发布，可用于 Meteor、NodeJS、 或静态浏览器应用程序。

安装

npm install simpl-schema 还有其他命名的 NPM 包 简单模式和简单模式。确保安装正确 包裹。 “simpl”上没有“e”。

所以 Typescript 中的正确导入如下所示：

import SimpleSchema from 'simpl-schema';

但是你的问题是关于打字的。 Meteor 打字的起点是 https://github.com/meteor-typescript/meteor-typescript-libs/tree/master/definitions 的 Meteor 打字库。
在其中，您会找到 collection2 和 simple-schema 的定义，但它是 old simple-schema。它们确实为您提供了一个很好的起点，并且您会想稍后再回来拿起 collection2 的。最终，经过大约一周的搜索/等。我根据 Meteor Git 上的原件编写了自己的集合。希望它们对未来的搜索者有所帮助，即使它们对您来说有点晚了。

对于奖励积分，这是验证方法的集合，您将在接下来寻找它：

declare module "meteor/mdg:validated-method" {
    declare class ValidatedMethod<T> extends MeteorValidatedMethod.ValidatedMethod<T> { }

    declare module MeteorValidatedMethod {
        export class ValidatedMethod<T> {
            constructor(options: ValidatedMethodOptions<T>);
            call(options?: T, cb?: (err, res)=> void): void;
        }

        interface ValidatedMethodOptions<T> {
            name: string;
            mixins?: Function[];
            validate: any;
            applyOptions: any;
            run(opts: T);
        }
    }
}
