const class web::FilePack

sys::Obj
  web::FilePack : web::Weblet

Source

FilePack is an in-memory cache of multiple text files to service static resources via HTTP. It takes one or more text files and creates one compound file. The result is stored in RAM using GZIP compression. Or you can use the pack utility method to store the result to your own files/buffers.

The onGet method is used to service GET requests for the bundle. The Content-Type header is set based on file extension of files bundled. It also implictly supports ETag/Last-Modified for 304 optimization.

The core factory is the makeFiles constructor. A suite of utility methods is provided for standard bundling of Fantom JavaScrit and CSS files.

makeFiles

static new makeFiles(File[] files, MimeType? mimeType := null)

Source

Construct a bundle for the given list of text files

onGet

virtual override Void onGet()

Source

Service an HTTP GET request for this bundle file

pack

static OutStream pack(File[] files, OutStream out)

Source

Pack multiple text files together and write to the given output stream. A trailing newline is automatically added if the file is missing one. Empty files are skipped. The stream is not closed. Return the given out stream.

toAppCssFiles

static File[] toAppCssFiles(Pod[] pods)

Source

Given a set of pods return a list of CSS files that form a complete Fantom application:

• flatten the pods using Pod.flattenDepends
• order them by dependencies using Pod.orderByDepends
• return toPodCssFiles

toAppJsFiles

static File[] toAppJsFiles(Pod[] pods)

Source

Given a set of pods return a list of JavaScript files that form a complete Fantom application:

• flatten the pods using Pod.flattenDepends
• order them by dependencies using Pod.orderByDepends
• insert toEtcJsFiles immediately after "sys.js"

toEtcJsFiles

static File[] toEtcJsFiles()

Source

Return the required sys etc files:

• add toMimeJsFile
• add toUnitsJsFile
• add toIndexPropsJsFile

toIndexPropsJsFile

static File toIndexPropsJsFile(Pod[] pods := Pod.list())

Source

Compile the indexed props database into a JavaScript file "index-props.js"

toLocaleJsFile

static File toLocaleJsFile(Locale locale, Pod[] pods := Pod.list())

Source

Compile the locale props into a JavaScript file "{locale}.js"

toMimeJsFile

static File toMimeJsFile()

Source

Compile the mime type database into a Javascript file "mime.js"

toPodCssFiles

static File[] toPodCssFiles(Pod[] pods)

Source

Map a set of pods to "/res/css/{name}.css" CSS files. Ignore pods that are missing a CSS file. This method does not flatten/order the pods.

toPodJsFile

static File? toPodJsFile(Pod pod)

Source

Get the standard pod JavaScript file or null if no JS code. The standard location used by the Fantom JS compiler is "/{pod-name}.js"

toPodJsFiles

static File[] toPodJsFiles(Pod[] pods)

Source

Map a set of pods to "/{name}.js" JavaScript files. Ignore pods that are missing a JavaScript file. This method does not flatten/order the pods.

toPodJsMapFile

static File toPodJsMapFile(File[] files, [Str:Obj]? options := null)

Source

Compile a list of pod JavaScript files into a single unified source map file. The list of files passed to this method should match exactly the list of files used to create the corresponding JavaScript FilePack. If the file is the standard pod JS file, then we will include an offset version of "{pod}.js.map" generated by the JavaScript compiler. Otherwise if the file is another JavaScript file (such as units.js) then we just add the appropiate offset.

The sourceRoot option may be passed in to replace "/dev/{podName}" as the root URI used to fetch source files from the server.

toTimezonesJsFile

@Deprecated { msg=... }
static File toTimezonesJsFile()

Source

Compile the timezone database into a JavaScript file "tz.js"

toUnitsJsFile

static File toUnitsJsFile()

Source

Compile the unit database into a JavaScript file "unit.js"
