1 | # Capistrano::FasterAssets
2 |
3 | This gem speeds up asset compilation by skipping the assets:precompile task if none of the assets were changed
4 | since last release.
5 |
6 | Works *only* with Capistrano 3+.
7 |
8 | ### Installation
9 |
10 | Add this to `Gemfile`:
11 |
12 | group :development do
13 | gem 'capistrano', '~> 3.1'
14 | gem 'capistrano-faster-assets', '~> 1.0'
15 | end
16 |
17 | And then:
18 |
19 | $ bundle install
20 |
21 | ### Setup and usage
22 |
23 | Add this line to `Capfile`, after `require 'capistrano/rails/assets'`
24 |
25 | require 'capistrano/faster_assets'
26 |
27 | ### Warning
28 |
29 | Please keep in mind, that if you use ERB in your assets, you might run into cases where Capistrano won't recompile assets when needed. For instance, let's say you have a CoffeeScript file like this:
30 |
31 | ```coffee
32 | text = <%= helper.get_text %>
33 | ```
34 |
35 | The assets might not get recompiled, even if they have to, as this gem only checks if the asset file has changed (which is probably the only safe/fast way to do this).
36 |
37 | ### More Capistrano automation?
38 |
39 | If you'd like to streamline your Capistrano deploys, you might want to check
40 | these zero-configuration, plug-n-play plugins:
41 |
42 | - [capistrano-unicorn-nginx](https://github.com/bruno-/capistrano-unicorn-nginx)
43 | no-configuration unicorn and nginx setup with sensible defaults
44 | - [capistrano-postgresql](https://github.com/bruno-/capistrano-postgresql)
45 | plugin that automates postgresql configuration and setup
46 | - [capistrano-rbenv-install](https://github.com/bruno-/capistrano-rbenv-install)
47 | would you like Capistrano to install rubies for you?
48 | - [capistrano-safe-deploy-to](https://github.com/bruno-/capistrano-safe-deploy-to)
49 | if you're annoyed that Capistrano does **not** create a deployment path for the
50 | app on the server (default `/var/www/myapp`), this is what you need!
51 |
