如何在自定义主题/插件中安装 npm 包

最后,对于同一任务中的某人。我通过以下方式使其生效:

  1. 关闭 content_security_policy 设置
  2. 以编程方式显式添加脚本(不使用 $.getScript,也不使用其他方法)。

一个有效的示例摘要片段如下(请将 web-component 替换为适合您情况的组件):

import { withPluginApi } from "discourse/lib/plugin-api";

let flag = false;

export default {
  name: "web-component",
  initialize() {
    withPluginApi("0.8", api => {
      api.onAppEvent("page:changed", () => {
        if (flag) return;

        addScript(
          "https://unpkg.com/web-component@0.0.1/dist/web-component/web-component.js",
          { defer: "", crossorigin: "anonymous" }
        );

        addWebComponent(
          "web-component",
          {
            id: "web-component"
          },
          `Hello world`
        );

        flag = true;
      });
    });
  }
};

function addWebComponent(tag, attrs, content) {
  var component = document.createElement(tag);

  Object.keys(attrs).forEach(key => {
    component.setAttribute(key, attrs[key]);
  });
  component.textContent = content;

  document.body.appendChild(component);
}

function addScript(src, attrs) {
  var script = document.createElement("script");

  script.setAttribute("src", src);

  Object.keys(attrs).forEach(key => {
    script.setAttribute(key, attrs[key]);
  });

  document.body.appendChild(script);
}
