Plan first, code second

You should know the code flow before writing anything

Plan for flexible and light architecture

Think about exposed APIs your module would need

Utilize Drupal’s best parts

Drupal is really good in text filtering, but only server-side (PHP code)

Paste Format uses Drupal text filtering features to filter the pasted text (and you rule what actually gets filtered and what stays in your content)

Tokens

Expose your module information to other modules

Examples HybridAuth and uLogin modules use it to expose

social information

Rules

Rules are ruling

Power and flexibility

Examples HybridAuth and uLogin Yandex Webmaster Original Texts

Views Bulk Operations

Batch API

Queue

Very useful for content manipulations

You just need to code the actual changes

Elements

Easy to reuse in any renderable array

#properties to control your element

Study drupal_render() to understand the rendering flow

‘#pre_render’ is really powerful

Plugins

Views, Panels use it – and you should

Flexible architecture

Eases maintenance and support (Image Editor)

Allows other developers to extend your module

Drupal 8 does the same

What a plugin is?

Array of properties utilized by another module

Properties may be function callbacks

S

Most popular content

Module design example

Most popular content

Always fresh statistics

By day, week, month

By content section on our site

No load on our servers

Is there a module for that?

Statistics provider

(plugins?)Popular URLs

URLs processor(plugins)

Popular entities(nodes, terms, you name it)

Views integration(Views handlers)

Any widget design
