BUILDING ROCKET.CHAT

Meteor Devshop

WHY?

Why not?

BOOM!

We've got noticed

Text

Our first week

And people liked it

REACTIVITY

IS

POWERFUL

LEARNED

THE HARD
WAY

keep records in memory to track what data each client have

More clients = More memory + More CPU

THE mergebox

NOt EVERYTHING needs mergebox

Prevent Merge Box
Starting an observer on server startup and send

messages to clients via stream instead use subscribe

and create one observe per client 

BLAZE GOT SLOW

WHY?

rendering

Can be expensive

Re-rendering TOO MANY TIMES

>1sec

HIDDEN = armage-DOM

+1000

OFF-DOM = speed

50ms

GRANULARITY

Not always needed

Computations, COMPUTATIONS, COMPUTATIONS

<template name="message">
  <li id="{{_id}}" class=" {{system}} {{t}} {{own}} {{isTemp}}"
    data-username="{{u.username}}" data-date="{{date}}">
    <span class="info">
      <span class="time">{{time}}</span>
    {{#if edited}}
      <span class="edited">({{_ "edited"}})</span>
    {{/if}}
    {{#if private}}
      <span class="private">{{_ "Only_you_can_see_this"}}</span>
    {{/if}}

    {{#if canEdit}}
      <i class="icon-pencil edit-message"></i>
    {{/if}}
    {{#if canDelete}}
      <i class="icon-trash-1 delete-message"></i>
    {{/if}}
    </span>
    <div class="body" dir="auto">
      {{{body}}}
    </div>
  </li>
</template>

{{#each message}}
    {{> message}}
{{/each}}

Less granularity, but that's ok!

<!-- With NRR -->
{{#each message}}
    {{#nrr nrrargs 'message' .}}{{/nrr}}
{{/each}}
html = ''

Tracker.nonreactive ->
    html = Blaze.toHTMLWithData content, data
    return html
