javascript - Gulp.js - 在变化时观察和编译 swig.js 模板文件

Question

我遇到了观看我的 Swig.js html 模板并在每次更改时编译它们的问题，为此我使用了 Gulp.js 任务运行器。这是我的 gulpfile.js:

var gulp = require('gulp');
var myth = require('gulp-myth');
var swig = require('gulp-swig');
var nodemon = require('gulp-nodemon');

gulp.task('styles', function () {
  gulp.src('./myth/*.css')
    .pipe(myth())
    .pipe(gulp.dest('./client/css'));
});

gulp.task('templates', function () {
  gulp.src('./views/*.html')
    .pipe(swig({ load_json: true }))
    .pipe(gulp.dest('./client'));
});

gulp.task('server', function () {
  gulp.run('styles');
  gulp.run('templates');

  gulp.src('./server.js').pipe(nodemon());

  gulp.watch('./myth/*.css', function () {
     gulp.run('styles');
  });

  gulp.watch('./views/*.html', function () {
     gulp.run('templates');
  }); 
});

Myth 任务 styles 运行良好 - 在每次更改 myth/*.css 时我都在 client/css 中更新了文件/..

但是名为 templates 的任务只给出一次结果。当我更改 client/index.html 中的 views/index.html 文件时，它仍然存在相同。在我的控制台中，我看到 templates 任务已运行，但结果仍然相同。

也许我遗漏了一些缓存选项或类似选项？!

Answer 1

Gulp-Swig 已更新为允许禁用缓存选项 - 以及设置其他 swig 默认值，如下所示。

gulp.task('templates', function() {
  gulp.src('./views/*.html')
    .pipe(swig({
      load_json: true,
      defaults: {
        cache: false,
        locals: {
          site_name: "My Blog"
        }
      }
    }))
    .pipe(gulp.dest('./client'));
});
