Microsoft.AspNet.Web.Optimization JavaScript捆绑无法最小化模板文字 [英] Microsoft.AspNet.Web.Optimization JavaScript bundling fails to minify template literals

问题描述

使用的最新版本 Microsoft.AspNet.Web.Optimization v1.1.3 如果包含模板文字。例如，如果我在捆绑脚本之一中包含以下内容：

Using the latest version of Microsoft.AspNet.Web.Optimization v1.1.3 I am unable to get bundling to minify the JavaScript if it includes template literals. For example if I include the following in one of my bundle scripts:

var name = 'Bob';
var formattedName = `${name} says hello`;

生成的捆绑包将加入所有文件，但不会缩小代码，并给我这个错误：

The resulting bundle will join all files but it won't minify code, and gives me this error:

/* Minification failed. Returning unminified contents.
(2,13-14): run-time error JS1014: Invalid character: `
(2,15-16): run-time error JS1004: Expected ';': {
(2,30-31): run-time error JS1014: Invalid character: `
(3,1-2): run-time error JS1107: Expecting more source characters
*/

我知道此功能仅在ECMAScript2015中引入，显然不支持此功能，但是除了恢复到该功能之外，还有其他解决方法

I understand this feature was only introduced in ECMAScript2015 and it's clearly not supported but is there a clean workaround other than reverting back to the old string concatenation methods?

var name = 'Bob';
var formattedName = name + ' says hello';

此外，模板文字支持将用于将来的 Microsoft.AspNet版本。 Web.Optimization ？

Also, will template literal support go into future versions of Microsoft.AspNet.Web.Optimization?

推荐答案

我正在使用 bundleconfig.json 方法，用于缩小一些脚本文件和运行适当的任务时遇到类似的错误：

I am using the bundleconfig.json method for minifying some script files and I encountered similar errors when running the appropriate task:

Illegal assignment: =
Expected ';'
Expected ';'
Expected expression
Expected '}'

我设法更改文字：

style.textContent = `
...
`;

到此：

style.textContent = `
...`;

它可能不会回答您的特定问题（使用Gulp时），但可能会帮助某个人，那是不想开始将npm的各种软件包用于同一目标。

It will probably not answer your specific question (as you used Gulp), but might help someone out there, that doesn't want to start using npm's various packages for the same objective.
