Angular Chart.js - 删除 Moment.js 作为依赖项/减少包大小 [英] Angular Chart.js - Remove Moment.js as Dependency / Reduce Bundle Size

问题描述

我正在使用 Chart.js 和 Angualar 7.

但是 Chart.js 为我的包大小增加了大约 450KB.通过其他资源我发现，Moment.js 是大尺寸的主要因素.

But Chart.js adds about 450KB to my bundle size. Through other resources I found out, that Moment.js is the main factor for the big size.

"chart.js": {
      "version": "2.7.3",
      "resolved": "https://registry.npmjs.org/chart.js/-/chart.js-2.7.3.tgz",
      "integrity": "sha512-3+7k/DbR92m6BsMUYP6M0dMsMVZpMnwkUyNSAbqolHKsbIzH2Q4LWVEHHYq7v0fmEV8whXE0DrjANulw9j2K5g==",
      "requires": {
        "chartjs-color": "^2.1.0",
        "moment": "^2.10.2"
      }
    },

我想知道如何从依赖项中删除 moment.js，以便减少包的大小.

I want to know how to remove moment.js from the dependencies, so that bundle size will be reduced.

Mybe 有没有办法只从 Chart.js 导入我真正使用的内容?

Mybe there is a way to only import what's I am really using from Chart.js?

推荐答案

您可以导入独立版本 - 不与以下行捆绑在一起:

You can import standalone version - not bundled one with the following line:

import Chart from 'chart.js/dist/Chart.js'

或者在 web.config 中设置别名:

Or setting alias in web.config:

resolve: {
    alias: {
      'chart.js': 'chart.js/dist/Chart.js'
    }
}

或者安装没有捆绑 moment.js 的 Angular ChartJS:

Or Install Angular ChartJS which does not have moment.js bundled:
