我正在用
Gulp创建一个静态站点生成器.我想知道如何将每个数据(JSON)传输到单个jade模板中以生成多个html文件.这是gulp’模板’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;
}
这是从我的所有内容生成的数据,并放入名为content.json的JSON结构化文件中

"projects": {
"title": "projects","body": ""
},"another": {
"title": "another","about": {

如您所见,来自’content.json’的数据很容易被解析并通过管道传输到我的jade模板中.我不知道如何使用数据生成多个html文件,并为每种类型的数据使用一个模板文件
例如：’pages.jade’将“应用”到content.json文件中的每个页面页面,并作为单独的html文件输出,如’about.html’,’anotherpage.html’.
如果您需要更多信息,请告诉我,非常感谢您花时间查看我的问题！

解决方法
我提出了两种可能的解决方案.我正在使用swig,但对于任何其他模板语言它应该是相同的.
第一个解决方案可能看起来有点’hackish’,因为它使用符号链接来“模拟”每个JSON文件的HTML模板.
也就是说,对于我们想要创建的每个HTML文件,我们都有一个符号链接指向我们的单个swig模板文件.所以,我们有：product-A.html – > product.swig.tpl,product-B.html – > product.swig.tpl,product-C.html – > product.swig.tpl等等(所有符号链接和swig模板都存储在_assets / html /文件夹中.
然后,我们在_assets / data /文件夹中有我们的JSON文件(product-A.json,product-B.json,product-C.json等).
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))
});
第二种解决方案使用gulp-foreach.
在这个例子中,_assets / html /中有一个模板(例如,product.html),然后,我们在_assets / data /上有一堆JSON文件(例如,product-A.json,product-B) .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',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))
})
)
});
所以,基本上,我们使用我们的JSON文件集创建一个流,对于每个文件,我们选择单个模板,从我们的JSON文件中获取数据并将其应用于模板.然后,我们在将缓冲区输出到目标之前重命名缓冲区,以避免每个循环在同一文件上写入(覆盖).然后,我们最终得到了_build / html上的一堆HTML文件：product-A.html,product-C.html,product-C.html
