使用require.js r.js调试优化的javascript

Question

没有r.js优化我的require js模块的所有工作。 但是使用优化的js文件...

r.js -o public/js/app.build.js

...其中app.build.js是......

({
    appDir: "../",
    baseUrl: "js",
    dir: "../../appdirectory-build",
    paths: {
        jquery: "./jquery-1.9.1",
        jade: "lib/requireJade"
    },
    modules: [
        {
            name: "main"
        }
    ]
})

...并且输出没有错误和警告......

r

...某些功能在我的页面上无效

所以我可以获得发生错误的行号：172。但问题是优化的main.js行号172的长度为206490。很难找到错误。

如何调试它并找到实际发生错误的地方？

没有任何优化我没有任何错误。通过优化，我得到错误和输出太差，无法调试此错误。

我尝试将excludeShallow与疑似错误文件

一起使用

r.js -o public/js/app.build.js excludeShallow=load_more_records

但是仍然会出现错误并且输出仍然相同。

为了使main.js更可调试，我在config中添加了optimize: "none"。

({
    appDir: "../",
    baseUrl: "js",
    dir: "../../appdirectory-build",
    paths: {
        jquery: "./jquery-1.9.1",
        jade: "lib/requireJade"
    },
    modules: [
        {
            name: "main"
        }
    ],
    optimize: "none"

})

此选项限制在一行中写入所有js。然后我看到了发生错误的实际行。并修复错误添加...

pragmasOnSave: {
      excludeJade : true
    }

... app.build.js写为here。

错误已修复。最终app.build.js：

({
    appDir: "../",
    baseUrl: "js",
    dir: "../../appdirectory-build",
    paths: {
        jquery: "./jquery-1.9.1",
        jade: "lib/requireJade"
    },
    modules: [
        {
            name: "main"
        }
    ],
    // optimize: "none",
    pragmasOnSave: {
      excludeJade : true
    }
})
