Usage subsReady

If you call subsReady without parameters it will check for all flow-router subscriptions to be ready. (It will not take into account the template level subscriptions you define)

If you pass parameters it will just check for this specific flow-router subscriptions to be ready. The parameters would be the subscription names you used when registering them on FlowRouter, like:

1FlowRouter.route('/posts', {
2    subscriptions: function(params, queryParams) {
3        this.register('posts', Meteor.subscribe('posts'));
4        this.register('items', Meteor.subscribe('items'));
5    }
6});

{{#if subsReady 'items' 'posts'}}
  <ul>
  {{#each items}}
    <li>{{title}}</li>
  {{/each}}
  </ul>
  <ul>
  {{#each posts}}
    <li>{{title}}</li>
  {{/each}}
  </ul>
{{/if}}

Usage isSubReady (deprecated)

Checks whether your subscription is ready. If you don't pass a subscription name it will check for all subscriptions.

{{#if isSubReady 'items'}}
  <ul>
  {{#each items}}
    <li>{{title}}</li>
  {{/each}}
  </ul>
{{/if}}

Usage pathFor

Used to build a path to your route. First parameter can be either the path definition or, since version 1.2.0 of flow-router, the name you assigned the route. After that you can pass the params needed to construct the path. Query parameters can be passed with the query parameter.

Notice: To deparameterize the query string we are currently using the not yet official accessor for the query lib in page.js via FlowRouter._qs

<a href="{{pathFor '/post/:id' id=_id}}">Link to post</a>
<a href="{{pathFor 'postRouteName' id=_id}}">Link to post</a>
<a href="{{pathFor '/post/:id/comments/:cid' id=_id cid=comment._id}}">Link to comment in post</a>
<a href="{{pathFor '/post/:id/comments/:cid' id=_id cid=comment._id query='back=yes&more=true'}}">Link to comment in post with query params</a>

Server side it can be used like this: FlowRouterHelpers.pathFor('/post/:id',{ id:'12345' })

Usage urlFor

Same as pathFor, returns absolute URL.

{{urlFor '/post/:id' id=_id}}

Usage linkTo

Custom content block for creating a link

{{#linkTo '/posts/'}}
  Go to posts
{{/linkTo}}

will return <a href="/posts/">Go to posts</a>

Usage param

Returns the value for a url parameter

<div>ID of this post is <em>{{param 'id'}}</em></div>

Usage queryParam

Returns the value for a query parameter

<input placeholder="Search" value="{{queryParam 'query'}}">

Usage currentRouteName

Returns the name of the current route

<div class={{currentRouteName}}>
  ...
</div>

Usage currentRouteOption

This adds support to get options from flow router

1FlowRouter.route("name", {
2  name: "yourRouteName",
3  action() {
4    BlazeLayout.render("layoutTemplate", {main: "main"});
5  },
6  coolOption: "coolOptionValue"
7});

<div class={{currentRouteOption 'customRouteOption'}}>
  ...
</div>
