如何使用Gulp和gulp-data从单一的玉石模板生成多个html文件

我正在用Gulp创build一个静态站点生成器。 我想知道如何pipe每个数据（JSON）到一个单一的玉模板产生多个HTML文件。 这里是吞咽'模板'的任务：

gulp.task('templates', function () { 'use strict'; var myData = JSON.parse(fs.readFileSync('./_assets/data/content.json')); var myPages = myData.pages; var myPosts = myData.posts; gulp.src('./_assets/templates/index.jade') .pipe(data(function (file) { return myData; })) .pipe(jade()) .pipe(minifyhtml()) .pipe(gulp.dest('./_site/')) .pipe(connect.reload()); // this is my dumb attempt at trying to // output each piece of data and than // have jade create an html file... for (var i in myPages) { gulp.src('./_assets/templates/page.jade') .pipe(data(function (file) { return myPages[i]; })) .pipe(jade()) .pipe(minifyhtml()) .pipe(gulp.dest('./_site/')) .pipe(connect.reload()); } }); function applyTemplate(data, template) { 'use strict'; // I was thinking maybe another function could // take care of applying a template to each json // data object in both 'posts' or 'pages' return; } 

这里是从我的所有内容中产生的数据，并将其放入名为content.json的JSON结构化文件中

 { "pages": { "projects": { "title": "projects", "body": "" }, "another": { "title": "another", "body": "" }, "about": { "title": "about", "body": "<p>This page is dedicated to the about me section of the site :).

正如你所看到的，来自'content.json'的数据很容易被parsing并传递给我的模板。 在哪里我倒下是如何产生多个HTML文件的数据和每个types的数据只使用一个模板文件

例如：“pages.jade”将被“应用”到content.json文件中的每页页面，并作为单独的html文件（如“about.html”，“anotherpage.html”）输出。

让我知道，如果你需要更多的信息，并感谢你太多花时间看我的问题！

我想出了两个可能的解决scheme。 我正在使用swig，但对其他任何模板语言都应该是一样的。

第一个解决scheme可能看起来有点'hackish'，因为它使用符号链接为我们的每个JSON文件“模拟”一个HTML模板。 也就是说，对于我们要创build的每个HTML文件，我们都有一个指向我们单个swig模板文件的符号链接。 所以，我们有： product-A.html -> product.swig.tpl ， product-B.html -> product.swig.tpl ， product-C.html -> product.swig.tpl等（所有的符号链接和swig模板存储在_assets/html/文件夹中。
然后，我们在_assets/data/文件夹（ product-A.json ， product-B.json ， product-C.json等）中有我们的JSON文件。

代码：

 var gulp = require('gulp'); var swig = require('gulp-swig'); var data = require('gulp-data'); var path = require('path'); var config = { html: { src: '_assets/html/*.html', dest: '_build/html' }, data: { src: '_assets/data/*.json' } } var getJsonData = function(file) { return require('./data/' + path.basename(file.path, path.extname(file.path)) + '.json'); }; gulp.task('templates', function() { return gulp.src(config.html.src) .pipe(data(getJsonData)) .pipe(swig()) .pipe(gulp.dest(config.html.dest)) }); 

第二个解决scheme使用gulp-foreach 。
在这个例子中，在_assets/html/ （例如product.html ）中有一个模板，然后在_assets/data/上有一堆JSON文件（例如， product-A.json ， product-B.json product-C.json ， product-C.json等）。

 var gulp = require('gulp'); var swig = require('gulp-swig'); var data = require('gulp-data'); var foreach = require('gulp-foreach'); var rename = require('gulp-rename'); var path = require('path'); var config = { html: { src: '_assets/html/*.html', dest: '_build/html' }, data: { src: '_assets/data/*.json' } } var getJsonData = function(file) { return require(file.path); }; gulp.task('templates', function() { return gulp.src(config.data.src) .pipe(foreach(function(stream, file){ var jsonFile = file; // We create this 'jsonFile' variable because the 'file' variable is overwritten on the next gulp.src. var jsonBasename = path.basename(jsonFile.path, path.extname(jsonFile.path)); return gulp.src(config.html.src) .pipe(data(getJsonData(jsonFile))) .pipe(swig()) .pipe(rename(function(htmlFile) { htmlFile.basename = jsonBasename; })) .pipe(gulp.dest(config.html.dest)) }) ) }); 

因此，基本上，我们使用我们的JSON文件集创build一个stream，并且为每个文件select单个模板，从我们的JSON文件中获取数据并将其应用于模板。 然后，我们重新命名缓冲区，然后输出它的目标，以避免每个循环写入（覆盖）在同一个文件。 然后，我们在_build/html上_build/html一堆HTML文件： product-A.html ， product-C.html ， product-C.html
