clojure - 如何让 cljsbuild 在 uberjar 编译 clojure 应用程序之前运行？

Question

我正在 clojure/clojurescript/reagennt 中制作同构应用程序。由于我依赖于 clojurescript 输出 js 文件进行服务器端渲染，因此我希望在 jar 之前编译该文件。我怎么做？

这是“lein uberjar”的输出，注意 jar 是首先编译的。我的 clj 文件“nash.clj”需要运行已编译的 server-side.js 版本:

还有我的project.clj...整个 cljsbuild 的事情目前对我来说还是个谜。

Answer 1

您必须添加 cljsbuild hooks在您的项目.clj 中:

:hooks [leiningen.cljsbuild]

关于您的 lein uberjar 输出，您说:

notice the jar is compiled first

事实并非如此。我按顺序看到以下任务的输出:- lein minify (或者任何被命名为缩小 css 的任务)- 莱因编译- lein cljsbuild 一次

我们无法从输出中判断 jar 任务是否在这些任务之前或之后运行，但这就是它的工作原理:默认情况下，uberjar 运行 clean -> javac -> 编译 -> jar

该钩子(Hook)使 cljsbuild 在 compile 任务之后运行。这就是为什么您在“编译 ClojureScript”之前看到“编译 bfa-clojure.api.auth...”的原因
