Instance Method Details

#asset_url(source) ⇒ `String`

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

It generates the relative or absolute URL for the given asset. It automatically decides if it has to use the relative or absolute depending on the configuration and current environment.

Absolute URLs are returned as they are.

It can be the name of the asset, coming from the sources or third party gems.

If Fingerprint mode is on, it returns the fingerprinted path of the source

If CDN mode is on, it returns the absolute URL of the asset.

‘subresource_integrity` modes are on and the asset is missing from the manifest

Examples:

Basic Usage


<%= asset_url "application.js" %>

# "/assets/application.js"

Alias


<%= asset_url "application.js" %>

# "/assets/application.js"

Absolute URL


<%= asset_url "https://code.jquery.com/jquery-2.1.4.min.js" %>

# "https://code.jquery.com/jquery-2.1.4.min.js"

Fingerprint Mode


<%= asset_url "application.js" %>

# "/assets/application-28a6b886de2372ee3922fcaf3f78f2d8.js"

CDN Mode


<%= asset_url "application.js" %>

# "https://assets.bookshelf.org/assets/application-28a6b886de2372ee3922fcaf3f78f2d8.js"

Parameters:

source (String, #url) —

the asset name or asset object

Returns:

(String) —

the asset path

Raises:

(Hanami::Assets::MissingManifestAssetError) —

if ‘fingerprint` or

Since:

2.1.0

# File 'lib/hanami/helpers/assets_helper.rb', line 694

def asset_url(source)
  return source.url if source.respond_to?(:url)
  return source if _absolute_url?(source)

  _context.assets[source].url
end

#audio_tag(source = nil, options = {}, &blk) ⇒ `Hanami::View::HTML::SafeString`

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Generate ‘audio` tag for given source

It accepts one string representing the name of the asset, if it comes from the application or third party gems. It also accepts strings representing absolute URLs in case of public CDN (eg. Bootstrap CDN).

Alternatively, it accepts a block that allows to specify one or more sources via the ‘source` tag.

If the “fingerprint mode” is on, ‘src` is the fingerprinted version of the relative URL.

If the “CDN mode” is on, the ‘src` is an absolute URL of the application CDN.

‘subresource_integrity` modes are on and the audio file is missing from the manifest

Examples:

Basic Usage


<%= audio_tag "song.ogg" %>

# <audio src="/assets/song.ogg"></audio>

#content_security_policy_nonce ⇒ `String`^?

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Random per request nonce value for Content Security Policy (CSP) rules.

If the ‘Hanami::Middleware::ContentSecurityPolicyNonce` middleware is in use, this helper returns the nonce value for the current request or `nil` otherwise.

For this policy to work in the browser, you have to add the ‘’nonce’‘ placeholder to the script and/or style source policy rule. It will be substituted by the current nonce value like `’nonce-A12OggyZ’.

Examples:

App configuration


config.middleware.use Hanami::Middleware::ContentSecurityPolicyNonce
config.actions.content_security_policy[:script_src] = "'self' 'nonce'"
config.actions.content_security_policy[:style_src] = "'self' 'nonce'"

View helper


<script nonce="<%= content_security_policy_nonce %>">

Returns:

(String, nil) —

nonce value of the current request

Since:

2.3.0

# File 'lib/hanami/helpers/assets_helper.rb', line 724

def content_security_policy_nonce
  return unless _context.request?

  _context.request.env[CONTENT_SECURITY_POLICY_NONCE_REQUEST_KEY]
end

#favicon_tag(source = DEFAULT_FAVICON, options = {}) ⇒ `Hanami::View::HTML::SafeString`

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Generate ‘link` tag application favicon.

If no argument is given, it assumes ‘favico.ico` from the application.

It accepts one string representing the name of the asset.

If the “fingerprint mode” is on, ‘href` is the fingerprinted version of the relative URL.

If the “CDN mode” is on, the ‘href` is an absolute URL of the application CDN.

‘subresource_integrity` modes are on and the favicon is file missing from the manifest

Examples:

Basic Usage


<%= favicon_tag %>

# <link href="/assets/favicon.ico" rel="shortcut icon" type="image/x-icon">

Custom Path


<%= favicon_tag "fav.ico" %>

# <link href="/assets/fav.ico" rel="shortcut icon" type="image/x-icon">

Custom HTML Attributes


<%= favicon_tag "favicon.ico", id: "fav" %>

# <link id="fav" href="/assets/favicon.ico" rel="shortcut icon" type="image/x-icon">

#image_tag(source, options = {}) ⇒ `Hanami::View::HTML::SafeString`

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Generate ‘img` tag for given source

‘alt` Attribute is auto generated from `src`. You can specify a different value, by passing the `:src` option.

If the “fingerprint mode” is on, ‘src` is the fingerprinted version of the relative URL.

If the “CDN mode” is on, the ‘src` is an absolute URL of the application CDN.

‘subresource_integrity` modes are on and the image file is missing from the manifest

#javascript_tag(*sources, **options) ⇒ `Hanami::View::HTML::SafeString`

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Generate ‘script` tag for given source(s)

It accepts one or more strings representing the name of the asset, if it comes from the application or third party gems. It also accepts strings representing absolute URLs in case of public CDN (eg. jQuery CDN).

If the “fingerprint mode” is on, ‘src` is the fingerprinted version of the relative URL.

If the “CDN mode” is on, the ‘src` is an absolute URL of the application CDN.

If the “subresource integrity mode” is on, ‘integrity` is the name of the algorithm, then a hyphen, then the hash value of the file. If more than one algorithm is used, they“ll be separated by a space.

If the Content Security Policy uses ‘nonce’ and the source is not absolute, the nonce value of the current request is automatically added as an attribute. You can override this with the ‘nonce: false` option. See #content_security_policy_nonce for more.
