ldcvmgr

ldcover manager.

Installation

npm install --save ldcvmgr

Usage

include required js file, and create a ldcvmgr instance:

ldcvmgr = new ldcvmgr({ ... });
ldcvmgr.get("some-cover-name").then( ... );

constructor options:

• path: where to find cache-missed ldcover html files. default /modules/cover
  • more information in the section below.
• loader: ldLoader compatible object for loading indicator when ldcvmgr is fetching remote ldcover html files.
  • default to a fullscreen ldLoader spinner, with class ldld full.
• autoInit: default false. init called automatically when set to true
• manager: block manager for loading @/plotdb/block style ldcover
• errorCover: customized cover for error handler. can either be a string or a @plotdb/block definition object.
• baseZ: baseZ for ldcover. if omitted, will be modal if zmgr is provided; otherwise will be 3000.
• zmgr: optional. zmgr for ldcover. see the zmgr package for more information.

API

• get(name, param): popup a ldcover name, and expect return value from it.
  • when name is a string, look up a ldcover named name in local cache or in "#{@path}/#name"
    • will also lookup up in local DOM for name in this selector: .ldcvmgr[data-name]
  • when name is an object, load it by @plotdb/block manager.
    • interface of the loaded block should be a ldcover object.
    • when available, {zmgr, baseZ} will be passed as block data, which should be used to maintain z-index.
  • when param is provided, it will be sent to on event as params.
• set(name, param): resolve popped ldcover name with param
• on(name, callback({...})): listen to name event. Following events are available:
  • on: fired when some ldcover is toggled on. callback params:
    • node: ldcover dom root.
    • params: additional parameters provided when get is called.
    • name: toggled ldcover name
  • off: fired when some ldcover is toggled off. similar params with on.
• lock(name): popup a ldcover name, and user can't dismiss it.
• purge(name): clear cache for ldcover name.
• toggle(name,value,param): toggle ldcover name with state based on the value (true or false)
  • optional param passed to on event, just like get.
• getcover(name): return ldcover instance of ldcover name.
• getdom(name): return DOM root of ldcover name.
• is-on(name): return true if ldcover name is on.

Customizing Path

The path option in constructor options should be either

• a string, representing the relative root of all ldcover html
• a function accepting a string

you can set path as function to make a more customizable behavior of ldcvmgr. For example, you can define name as:

locale@variant@name

and invoke ldcvmgr.get like this:

zh-tw@depart-1024@logout

this is an abstract name and there is nothing to do with server file structure, however you can convert it with path function into something like this:

/ldcv/zh-tw/depart-1024/logout.html

furthermore, you can also config your reverse proxy to lookup files ( nginx config for example ):

location /ldcv/(?<lc>.+)/(?<dep>.+)/(?<name>.+) {
  try_files /intl/$lc/ldcv/$dep/$name.html /intl/$lc/ldcv/generic/$name.html /ldcv/generic/$name.html =404;
}

Toggling without scripting

By auto-init and adding data-ldcvmgr-toggle attributes, you can toggle ldcover automatically when the node with required attribute clicked. Content of the attribute will be used to look up ldcover, which can be either:

• a string, doesn't contain : - will be treated as a plain ldcover name.
• a string, contains : - will be treated as an id of a block, and converted back to a block definition object.
