[英]How I replace values in HTML attributes via config.json file with Gulp?
Let's say I have a JSON file with the pairs: 假设我有一个带有对的JSON文件:
{
"Table":{
"fullwidth": "680",
"color": "#33d025",
"margin1": "30",
"margin2": "60",
"padding": "20"
}
}
then, I want to read those values and use them to replace attributes in an html file that looks like this: 然后,我想读取这些值,并使用它们替换如下所示的html文件中的属性:
<table width="{{Table.fullwidth}}" bgcolor="{{Table.color}}" style="margin: {{Table.margin1}}px {{Table.margin2}}px;">
<tr>
<td style="padding: {{Table.padding}}px;">
<img src="a.jpg">
</td>
</tr>
</table>
So, with the html file in a "temp/" path, after gulping, I obtain a valid html file in "dist/" with the attributes changed looking like this: 因此,将html文件放在“ temp /”路径中,经过吞食后,我在“ dist /”中获得了一个有效的html文件,其属性已更改,如下所示:
<table width="680" bgcolor="#33d025" style="margin: 30px 60px;">
<tr>
<td style="padding: 20px;">
<img src="a.jpg">
</td>
</tr>
</table>
I have already tried gulp-token-replace but after running it once, it won't work again if I save new values in the json file, even when it triggers the watch function, forcing me to restart the "gulp". 我已经尝试过gulp-token-replace,但是运行它一次之后,如果我将新值保存在json文件中,即使它触发了watch函数,也将无法再次工作,迫使我重新启动“ gulp”。
Is there a gulp plugin that can do this? 有一个gulp插件可以做到这一点吗? or a technique that can replace the gulp-token-replace? 或可以替换掉gulp-token-replace的技术?
Maybe just javascript, but, can I run something like that from inside a gulp process (running watch to refresh it)? 也许只是javascript,但是,我可以在gulp进程中运行类似的东西(运行手表以刷新它)吗?
Gulpfile.js as requested: 根据要求提供Gulpfile.js:
// Include gulp
var gulp = require('gulp'),
// Include plugins
fileinclude = require('gulp-file-include'),
rename = require('gulp-rename'),
images = require('gulp-imagemin'),
cache = require('gulp-cache'),
browserSync = require('browser-sync').create(),
reload = browserSync.reload,
runSequence = require('run-sequence'),
del = require('del'),
notify = require('gulp-notify'),
gtr = require('gulp-token-replace')
// Default Task
gulp.task('default', function (cb) {
runSequence('clean', ['AA', 'BB', 'CC', 'watch'], cb);
});
// TASKS
// Clean 'dist'
gulp.task('clean', function () {
return del(['HTMLTemplates/*.html', 'HTMLTemplates/img', 'Temp/*.html']);
});
// Compress images
gulp.task('BB', function () {
gulp.src('templates/img/*.{gif,jpg,png}')
.pipe(cache(images({
optimizationLevel: 4,
progressive: true,
interlaced: true
})))
.pipe(gulp.dest('Templates/img/'));
});
// Reload browser
gulp.task('reload', function () {
browserSync.reload();
});
// Prepare Browser-sync
gulp.task('CC', ['AA'], function () {
browserSync.init({
// browserSync.init(['templates/*/*.html'], {
//proxy: 'your_dev_site.url'
server: {
baseDir: './HTMLTemplates'
}
});
});
// MAIN TASKS
gulp.task('AA', function (cbk) {
runSequence('fileinclude', 'trp', cbk);
});
// Force to run fileinclude first before replacing the tokens
gulp.task('trp', ['fileinclude'], function (done) {
function onFinish(event) {
if (event.task === 'tokenreplace') {
gulp.removeListener('task_stop', onFinish);
done();
}
}
gulp.on('task_stop', onFinish);
gulp.start('tokenreplace');
});
// Include partial files into email template (fileinclude)
gulp.task('fileinclude', function () {
// grab 'template'
return gulp.src('templates/layouts/*.tpl.html')
// include partials
.pipe(fileinclude({
basepath: 'templates/components/'
}))
// remove .tpl.html extension name
.pipe(rename({
extname: ""
}))
// add new extension name
.pipe(rename({
extname: ".html"
}))
// move file to folder
.pipe(gulp.dest('Temp/'))
.pipe(notify({
message: 'Template file includes complete'
}));
});
// Replace tokens in the index.html created by fileinclude
gulp.task('tokenreplace', ['fileinclude'], function (doit) {
var config = require('./templates/components/000 vars/config.json');
return gulp.src('Temp/index.html')
.pipe(gtr({
global: config
}))
.pipe(gulp.dest('HTMLTemplates/'))
// notify to say the task has complete
.pipe(browserSync.stream())
.pipe(notify({
message: 'Vars includes complete'
})), doit();
});
// END of MAIN TASKS
// WATCH
// Watch files for changes in html/css/tpl.html/images
gulp.task('watch', function () {
gulp.watch(['templates/components/**/*.html'], ['AA']);
gulp.watch(['templates/components/**/*.css'], ['AA']);
gulp.watch(['templates/layouts/*.tpl.html'], ['AA']);
gulp.watch(['templates/components/000 vars/*.json'], ['trp']);
gulp.watch(['HTMLTemplates/*.html'], ['reload']);
gulp.watch('templates/img/*', ['BB']);
});
I received the answer directly from the developer of the Gulp Token Replace plugin, so I'm answering my own question for archive purposes. 我直接从Gulp令牌替换插件的开发人员那里得到了答案,因此出于存档目的,我在回答自己的问题。
Replace this: 替换为:
// Replace tokens in the index.html created by fileinclude
gulp.task('tokenreplace', ['fileinclude'], function (doit) {
var config = require('./templates/components/000 vars/config.json');
return gulp.src('Temp/index.html')
.pipe(gtr({
global: config
}))
with this: 有了这个:
// Replace tokens in the index.html created by fileinclude
gulp.task('tokenreplace', ['fileinclude'], function (doit) {
delete require.cache[require.resolve('./templates/components/000 vars/config.json')]
var config = require('./templates/components/000 vars/config.json');
return gulp.src('Temp/index.html')
.pipe(gtr({
global: config
}))
And now it works like a charm! 现在,它就像一种魅力!
