Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

描述

该库获取由webpack构建过程生成的单独声明资产文件,并将它们捆绑到一个单独的声明文件中。但是,它通过重新组合单独的声明来实现,就好像所有类和接口都被定义为 内部模块 一样。因此,如果您自己将类和接口公开给全局模块空间,那么使用此插件才有意义。

警告

这是一个有趣的设置,你可能只想使用内部模块或外部模块,然后这个库将没有用,除了作为灵感来制作另一个组合声明文件的插件。

什么时候使用这个

该插件具有如下设置,允许外部模块模仿内部模块。创建的用例是将模块加载到单独的文件中,同时还能够将前缀URI(如foaf:Image)映射回模块路径(my.modules.rdfs.Image)。只有在极少数情况下你想做类似的事情,这可能会有所帮助。

选项:

  1. out:应该保存组合声明文件的路径。
  2. moduleName:要生成的内部模块的名称
  3. excludedReferences:一个数组,您希望从最终声明文件中排除引用。

要求:

这个插件是作为ts-loader的扩展而开发的, 当declaration设置为-时 truetsconfig.json为每个源文件生成单独的声明文件。理论上,它应该与任何生成声明文件作为输出的加载器一起使用。

以下是一个示例设置:

//init.ts
import Foo = require('./foo');
import Foo2 = require('./foo2');
var register:Function = (function()
{
    some.path['moduleName'] = {
        "Foo": Foo,
        "Foo2" : Foo2,
    }
    return function(){};
})();
export = register;

//foo.ts
export class Foo {
    bar():boolean { return true; }
}

//foo2.ts
import Foo = require('./foo');
export class Foo2 extends Foo {
    bar():boolean { return true; }
}

生成(当使用typescript编译器的declaration = true标志时)

//init.d.ts
var register: Function;
export = register;

//foo.d.ts
declare class Foo {
    bar():boolean;
}
export = Foo;

//foo2.d.ts
import Foo = require('./foo');
declare class Foo2 extends Foo{
    bar():boolean;
}
export = Foo2;

其中包含以下webpack.config.js

var DeclarationBundlerPlugin = require('declaration-bundler-webpack-plugin');
module.exports = {
    entry: './src/init.ts',
    output: {
        filename: './builds/bundle.js'
    },
    resolve: {
        extensions: ['', '.ts', '.tsx','.webpack.js', '.web.js', '.js']
    },
    module: {
        loaders: [
            { test: /\.ts(x?)$/, loader: 'ts-loader' }
        ]
    },
    watch:true,
    plugins: [
        new DeclarationBundlerPlugin({
            moduleName:'some.path.moduleName',
            out:'./builds/bundle.d.ts',
        })
    ]
}

将变成: //bundle.d.ts declare module some.path.moduleName {

    var register: Function;

    class Foo {
        bar():boolean;
    }

    class Foo2 extends Foo {
        bar():boolean;
    }
}

使用此设置和生成的声明文件,其他想要使用此模块的模块可以添加对生成的bundle.d.ts的引用。然后,他们可以访问模块的所有类,就好像它们是在全局路径中定义的一样,如内部打字稿模块:

///<reference path="path/to/bundle.d.ts" />
var foo:some.path.moduleName.Foo = new some.path.moduleName.Foo();

当您最终在浏览器中加载bundle.js时,将自动调用register函数,这将使类在全局模块路径中可用,以便其他模块可以按照它们从声明文件中所期望的那样访问类。
