发布扩展

¥Publishing an extension

如果你计划发布 Chart.js 的扩展，这里有一些建议。

¥If you are planning on publishing an extension for Chart.js, here are some pointers.

Awesome

你可能希望你的扩展名列在 awesome (opens new window)。

¥You'd probably want your extension to be listed in the awesome (opens new window).

请注意 30 天的最低延期年龄要求。

¥Note the minimum extension age requirement of 30 days.

ESM

如果你正在使用 ESM，你可能仍想发布扩展的 UMD 包。因为 Chart.js v3 是 tree shakeable，界面有点不同。UMD 包的全局 Chart 包含所有内容，而 ESM 包单独导出所有内容。幸运的是，大多数导出都可以由打包器自动映射。

¥If you are utilizing ESM, you probably still want to publish a UMD bundle of your extension. Because Chart.js v3 is tree shakeable, the interface is a bit different. UMD package's global Chart includes everything, while ESM package exports all the things separately. Fortunately, most of the exports can be mapped automatically by the bundlers.

但不是帮手。

¥But not the helpers.

在 UMD 中，可以通过 Chart.helpers 获得助手。在 ESM 中，它们是从 chart.js/helpers 导入的。

¥In UMD, helpers are available through Chart.helpers. In ESM, they are imported from chart.js/helpers.

例如，对于 UMD，import {isNullOrUndef} from 'chart.js/helpers' 在 Chart.helpers.isNullOrUndef 可用。

¥For example import {isNullOrUndef} from 'chart.js/helpers' is available at Chart.helpers.isNullOrUndef for UMD.

Rollup

output.globals 可用于转换助手。

¥output.globals can be used to convert the helpers.

module.exports = {
  // ...
  output: {
    globals: {
      'chart.js': 'Chart',
      'chart.js/helpers': 'Chart.helpers'
    }
  }
};
