Angular 6 template cache problem (for html files) on gulp build

Question

We have template cache problem for html files and we would like to solve it without deleting the cache data(If we delete it, we see performance issue). Do you have any suggestions for it ?

Answer 1

Thanks for your answer, but our solution is little different. In our company, we use weblogic server and When we deploy the app, it creates all resources in specific folder and again and again(It holds previous ones). After deleting the unnecessary resources, the app start to work properly.

Answer 2

One good solution for your problem is called file revision or Hashing, this approach concept is:

simply rename every html/js/img file served by our app by concatenating a random-hash before the file extension

There are many possible ways doing that. One good way is this 3 steps:

Step 1. Creating revision:rename gulp task

    gulp.task(“revision:rename”, [“compile”], () =>
      gulp.src(["dist/**/*.html",
                "dist/**/*.css",
                "dist/**/*.js",
                "dist/**/*.{jpg,png,jpeg,gif,svg}"])
      .pipe(rev())
      .pipe(revdel())
      .pipe(gulp.dest(“dist”))
      .pipe(rev.manifest({ path: “manifest.json” }))
      .pipe(gulp.dest(“dist”))
    );

Step 2. Creating revision:updateReferences gulp task

    gulp.task(“revision:updateReferences”, [“compile”, “revision:rename”], () =>
      gulp.src([“dist/manifest.json”,”dist/**/*.{html,json,css,js}”])
      .pipe(collect())
      .pipe(gulp.dest(“dist”))
    );

Step 3. Creating compile:production gulp task

    gulp.task(“compile:production”, [“compile”, “revision:rename”, “revision:updateReferences”]);
