如何讓cljsbuild在uberjar之前運行以編譯Clojure應用程序？

Question

我正在使用clojure / clojurescript / reagennt開發一個同構應用程序。 由於我依賴於clojurescript輸出js文件進行服務器端渲染，因此我希望在jar之前先編譯該文件。 我怎么做？

這是“ lein uberjar”的輸出，請注意，該jar首先被編譯。 我的clj文件“ nash.clj”需要運行已編譯的server-side.js構建：

而我的project.clj ...整個cljsbuild東西目前對我來說還是個謎。

Answer 1

您必須在project.clj中添加cljsbuild掛鈎 ：

:hooks [leiningen.cljsbuild]

關於您的lein uberjar輸出，您說：

注意jar首先被編譯

那不是正在發生的事情。 我依次看到以下任務的輸出：-lein minify（或最小化css的任務命名）-lein編譯-lein cljsbuild一次

我們不能從輸出說如果jar任務前或完成這些任務之后運行，但它是如何工作：在默認情況下，uberjar運行clean - > javac - > compile - > jar

該鈎子使cljsbuild在compile任務之后運行。 這就是為什么在“ Compile ClojureScript”之前看到“ Compiling bfa-clojure.api.auth ...”
