.SH "NAME"
Mojolicious::Static \- Serve static files
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&  use Mojolicious::Static;
\&
\&  my $static = Mojolicious::Static\->new;
\&  push @{$static\->classes}, \*(AqMyApp::Controller::Foo\*(Aq;
\&  push @{$static\->paths}, \*(Aq/home/sri/public\*(Aq;
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Mojolicious::Static is a static file server with \f(CW\*(C`Range\*(C'\fR, \f(CW\*(C`If\-Modified\-Since\*(C'\fR and \f(CW\*(C`If\-None\-Match\*(C'\fR support, based
on \s-1RFC 7232\s0 <https://tools.ietf.org/html/rfc7232> and \s-1RFC 7233\s0 <https://tools.ietf.org/html/rfc7233>.
.SH "ATTRIBUTES"
.IX Header "ATTRIBUTES"
Mojolicious::Static implements the following attributes.
.SS "asset_dir"
.IX Subsection "asset_dir"
.Vb 2
\&  my $dir = $static\->asset_dir;
\&  $static = $static\->asset_dir(\*(Aqassets\*(Aq);
.Ve
.PP
Subdirectory used for all static assets, defaults to \f(CW\*(C`assets\*(C'\fR.
.SS "classes"
.IX Subsection "classes"
.Vb 2
\&  my $classes = $static\->classes;
\&  $static     = $static\->classes([\*(Aqmain\*(Aq]);
.Ve
.PP
Classes to use for finding files in \f(CW\*(C`DATA\*(C'\fR sections with Mojo::Loader, first one has the highest precedence,
defaults to \f(CW\*(C`main\*(C'\fR. Only files with exactly one extension will be used, like \f(CW\*(C`index.html\*(C'\fR. Note that for files to be
detected, these classes need to have already been loaded and added before \*(L"warmup\*(R" is called, which usually happens
automatically during application startup.
.PP
.Vb 2
\&  # Add another class with static files in DATA section
\&  push @{$static\->classes}, \*(AqMojolicious::Plugin::Fun\*(Aq;
\&
\&  # Add another class with static files in DATA section and higher precedence
\&  unshift @{$static\->classes}, \*(AqMojolicious::Plugin::MoreFun\*(Aq;
.Ve
.SS "extra"
.IX Subsection "extra"
.Vb 2
\&  my $extra = $static\->extra;
\&  $static   = $static\->extra({\*(Aqfoo/bar.txt\*(Aq => \*(Aq/home/sri/myapp/bar.txt\*(Aq});
.Ve
.PP
Paths for extra files to be served from locations other than \*(L"paths\*(R", such as the images used by the built-in
exception and not found pages. Note that extra files are only served if no better alternative could be found in
\&\*(L"paths\*(R" and \*(L"classes\*(R".
.PP
.Vb 2
\&  # Remove built\-in favicon
\&  delete $static\->extra\->{\*(Aqfavicon.ico\*(Aq};
.Ve
.SS "paths"
.IX Subsection "paths"
.Vb 2
\&  my $paths = $static\->paths;
\&  $static   = $static\->paths([\*(Aq/home/sri/public\*(Aq]);
.Ve
.PP
Directories to serve static files from, first one has the highest precedence.
.PP
.Vb 2
\&  # Add another "public" directory
\&  push @{$static\->paths}, \*(Aq/home/sri/public\*(Aq;
\&
\&  # Add another "public" directory with higher precedence
\&  unshift @{$static\->paths}, \*(Aq/home/sri/themes/blue/public\*(Aq;
.Ve
.SS "prefix"
.IX Subsection "prefix"
.Vb 2
\&  my $prefix = $static\->prefix;
\&  $static    = $static\->prefix(\*(Aq/static\*(Aq);
.Ve
.PP
Prefix to use for all static files, defaults to \f(CW\*(C`undef\*(C'\fR. This can be very useful for production deployments where the
reverse proxy server should take over serving static files.
.SH "METHODS"
.IX Header "METHODS"
Mojolicious::Static inherits all methods from Mojo::Base and implements the following new ones.
.SS "asset_path"
.IX Subsection "asset_path"
.Vb 1
\&  my $path = $static\->asset_path(\*(Aq/app.js\*(Aq);
.Ve
.PP
Get static asset path.
.SS "dispatch"
.IX Subsection "dispatch"
.Vb 1
\&  my $bool = $static\->dispatch(Mojolicious::Controller\->new);
.Ve
.PP
Serve static file for Mojolicious::Controller object.
.SS "file"
.IX Subsection "file"
.Vb 2
\&  my $asset = $static\->file(\*(Aqimages/logo.png\*(Aq);
\&  my $asset = $static\->file(\*(Aq../lib/MyApp.pm\*(Aq);
.Ve
.PP
Build Mojo::Asset::File or Mojo::Asset::Memory object for a file, relative to \*(L"paths\*(R" or from \*(L"classes\*(R",
or return \f(CW\*(C`undef\*(C'\fR if it doesn't exist. Note that this method uses a relative path, but does not protect from
traversing to parent directories.
.PP
.Vb 1
\&  my $content = $static\->file(\*(Aqfoo/bar.html\*(Aq)\->slurp;
.Ve
.SS "file_path"
.IX Subsection "file_path"
.Vb 1
\&  my $path = $static\->file_path(\*(Aq/index.html\*(Aq);
.Ve
.PP
Get static file path with \*(L"prefix\*(R" if it has been configured.
.SS "is_fresh"
.IX Subsection "is_fresh"
.Vb 3
\&  my $bool = $static\->is_fresh(Mojolicious::Controller\->new, {etag => \*(Aqabc\*(Aq});
\&  my $bool = $static\->is_fresh(
\&    Mojolicious::Controller\->new, {etag => \*(AqW/"def"\*(Aq});
.Ve
.PP
Check freshness of request by comparing the \f(CW\*(C`If\-None\-Match\*(C'\fR and \f(CW\*(C`If\-Modified\-Since\*(C'\fR request headers to the \f(CW\*(C`ETag\*(C'\fR
and \f(CW\*(C`Last\-Modified\*(C'\fR response headers.
.PP
These options are currently available:
.IP "etag" 2
.IX Item "etag"
.Vb 2
\&  etag => \*(Aqabc\*(Aq
\&  etag => \*(AqW/"abc"\*(Aq
.Ve
.Sp
Add \f(CW\*(C`ETag\*(C'\fR header before comparing.
.IP "last_modified" 2
.IX Item "last_modified"
.Vb 1
\&  last_modified => $epoch
.Ve
.Sp
Add \f(CW\*(C`Last\-Modified\*(C'\fR header before comparing.
.SS "serve"
.IX Subsection "serve"
.Vb 2
\&  my $bool = $static\->serve(Mojolicious::Controller\->new, \*(Aqimages/logo.png\*(Aq);
\&  my $bool = $static\->serve(Mojolicious::Controller\->new, \*(Aq../lib/MyApp.pm\*(Aq);
.Ve
.PP
Serve a specific file, relative to \*(L"paths\*(R" or from \*(L"classes\*(R". Note that this method uses a relative path, but
does not protect from traversing to parent directories.
.SS "serve_asset"
.IX Subsection "serve_asset"
.Vb 1
\&  $static\->serve_asset(Mojolicious::Controller\->new, Mojo::Asset::File\->new);
.Ve
.PP
Serve a Mojo::Asset::File or Mojo::Asset::Memory object with \f(CW\*(C`Range\*(C'\fR, \f(CW\*(C`If\-Modified\-Since\*(C'\fR and \f(CW\*(C`If\-None\-Match\*(C'\fR
support.
.SS "warmup"
.IX Subsection "warmup"
.Vb 1
\&  $static\->warmup();
.Ve
.PP
Prepare static files from \*(L"classes\*(R" and static assets for future use.
