Meteor's Iron Router - Route multiple paths to one template but still DRY

问题

I want to route multiple paths to the same template. For example, /abc/home and /home will both show the home template. The paths can also have subpaths, so abc/parent/child and /parent/child should route to same path also.

I can simply repeat:

Router.route('/home', function () {
  this.render('home');
  Session.set('menu', 'home');
});
Router.route('/abc/home', function () {
  this.render('home');
  Session.set('menu', 'home');
});

But I don't want to repeat it. If I want to change the template to route to, I want to only change it once - for convenience and also to minimize errors.

I can also use parameters:

Router.route('/:_abc/:path', function () {
  if(this.params._abc == 'abc') {
    switch(this.params.path) {
      case 'home':
        this.render('home');
        break;
      case 'someotherroute':
        this.render('someotherroute');
        break;
    }
  }
});

But this, again, is repeating myself. Also, there can subpaths, and I don't want to define routing for /:_abc/:parent/:children and /:_abc/:grandparent/:parent/:children/:, because it will be messy.

I also tried using Router.go():

Router.route('/:_abc/:route', function () {
  if(this.params._abc == 'abc') {
    Router.go('/' + this.params.route);
  }
});

But this removes the /abc/ from the url, which is undesired in my case.

The best solution I have right now is using a shared function:

var renderHome = function () {
  this.render('home');
  Session.set('menu', 'home');
}

Router.route('/home', renderHome());
Router.route('/abc/home', renderHome());

Can I instead do something like specify an array, or comma-separated string:

Router.route(['/home', '/abc/home'], function () {
  this.render('home');
  Session.set('menu', 'home');
});

// or

Router.route('/home, /abc/home', function () {
  this.render('home');
  Session.set('menu', 'home');
});

How do I efficiently route multiple paths to one template, while not repeating myself?

回答1:

Use a regular expression (regex) that matches both /home and /abc/home.

回答2:

I made a second template that only includes the first. In your case this might look like this:

<template name="abcHome">
  {{> home}}
</template>
