data hook

data(params, qs)

• params {Object} - Serialized route parameters, /route/:_id => { _id: 'str' }
• qs {Object} - Serialized query string, /route/?key=val => { key: 'val' }
• Return: {Mongo.Cursor|Object|[Object]|false|null|void}

.data() is triggered right after all resources in .waitOn() and .waitOnResources() hooks are ready.

FlowRouter.route('/post/:_id', {
  name: 'post',
  waitOn(params) {
    return Meteor.subscribe('post', params._id);
  },
  data(params, qs) {
    return PostsCollection.findOne({_id: params._id});
  }
});

Passing data into a Template

FlowRouter.route('/post/:_id', {
  name: 'post',
  action(params, qs, post) {
    this.render('_layout', 'post', { post });
  },
  waitOn(params) {
    return Meteor.subscribe('post', params._id);
  },
  data(params, qs) {
    return PostsCollection.findOne({_id: params._id});
  }
});

<!-- in a template -->
<template name="post">
  <h1>{{post.title}}</h1>
  <p>{{post.text}}</p>
</template>

Data in other hooks

Returned value from data hook, will be passed into all other hooks as third argument and to triggersEnter hooks as fourth argument

FlowRouter.route('/post/:_id', {
  name: 'post',
  data(params) {
    return PostsCollection.findOne({_id: params._id});
  },
  triggersEnter: [(context, redirect, stop, data) => {
    console.log(data);
  }]
});
