从Webpack的require.context中排除文件 [英] Exclude files from require.context of Webpack

问题描述

我正在尝试在Webpack的 require.context 中包含伊斯坦布尔记者应该涵盖的所有文件。

I'm trying to include in with require.context of Webpack all the files that should be covered by my Istanbul reporter.

我想包含/要求 app 下没有 .test.js extension。

I would like to include/require all the files under app that have not the .test.js extension.

// internals/testing/test-bundler.js
const context = require.context('../../app', true, /^.*(?!(\.test|internals.*))\.js$/);
context.keys().forEach(context);

我的文件结构是：

app/components/
app/containers/
app/decorators/
app/orm/
app/pages/
app/store/
app/tests/
app/utils/
app/app.js
app/reducers.js
app/routes.js
internals/testing/test-bundler.js

显然我的正则表达式不起作用，因为在报道报告中我查看所有 .test.js 文件，甚至 internals / testing / test-bundler.js 文件。

Obviously my regex doesn't work because inside the coverage report I see all the .test.js files and even the internals/testing/test-bundler.js file.

我做错了什么？

推荐答案

你需要注意一下负面的前瞻部分采用了哪种方式拒绝。如果你在第一个正斜杠之后立即执行它可以正常工作。

You need to be aware after what part the negative lookahead employs it's rejection. If you do it right after the first forward slash it works fine.

并且你要拒绝。* test 斜杠之后，而不是直接在它后面的 test 。

And with that you want to reject .*test after the slash, instead of just test directly behind it.

/^(?!internals).*\/(?!.*test).*\.js$/

或更具体地说，路径名中不允许 internals 。

也不以<$结尾c $ c> test.js ：

Or more specific not allowing internals in the path name.
Nor ending with test.js:

^(?!.*(?:internals|test.js$)).*\.js$
