Node API for executing the XML/HTML to PDF renderer
PrinceXML via prince CLI.
This is a Node API for executing the
XML/HTML to PDF renderer PrinceXML CLI prince from within
JavaScript. The essential point of this Node extension is not primarily
to just abstract away the asynchronous CLI execution. Instead there
are two other major points: First, this Node extension provides a
fixed dependency, as other Node extensions which require PrinceXML can
just depend (via their NPM package.json file) onto this extension.
Second, as this Node extension can — across platforms —
automatically download, locally unpack and use a PrinceXML distribution,
there is no need for any previously available global PrinceXML
installation. Just depend on this Node extension and PrinceXML is
available!
Use the Node Package Manager (NPM) to install this module
locally (default) or globally (with option -g):
$ npm install [-g] prince
ATTENTION: In case you are behind a corporate firewall, you usually
have to configure your corporate proxy before installing this module.
For this, either configure the proxy inside NPM (e.g. npm config set proxy http://proxy.example.com:3128)
or alternatively set the environment variable http_proxy (e.g. export http_proxy=http://proxy.example.com:3128).
NOTICE: PrinceXML provides just distribution-specific and dynamically
linked Linux binaries. The Node-Prince installation procedure tries to
detect your particular distribution on npm install [-g] prince and
downloads the corresponding binary. But because of the dynamic linking
of PrinceXML binaries, it still can be that you first have to install
some distribution-specific system dependencies. For instance, under
Debian 8.0 you first have to install the necessary system packages with
apt-get install nodejs nodejs-legacy npm libgif4 curl.

Prince([options]): Prince: constructor for the API. Call this once for every XML/HTML to PDF conversion process. This returns the Prince API for further method chaining. -
Prince#binary(binary): Prince: set the path to the prince(1) binary. By default it isprince(in case PrinceXML was found globally installed at the Node API installation time) or the path to theprincebinary of the locally installed PrinceXML distribution (in case PrinceXML was not found globally installed at the Node API installation time). This returns the Prince API for further method chaining. -
Prince#prefix(prefix): Prince: set the path to the PrinceXML installation. This by default is either empty (in case PrinceXML was found globally installed at the Node API installation time) or the path to the locally installed PrinceXML distribution (in case PrinceXML was not found globally installed at the Node API installation time). This returns the Prince API for further method chaining. -
Prince#license(filename): Prince: set the path to the PrinceXML license file. This by default uses the pathlicense/license.datunder the PrinceXML installation. This returns the Prince API for further method chaining. -
Prince#timeout(timeout): Prince: set the execution timeout in milliseconds. The by default it is10000(10s). This returns the Prince API for further method chaining. -
Prince#maxbuffer(maxbuffer): Prince: set the execution maximum stdout/stderr buffer size in bytes. The by default it is10485760(10MB). This returns the Prince API for further method chaining. -
Prince#cwd(dirname): Prince: set the current working directory for execution. The by default it is.(current working directory). This returns the Prince API for further method chaining. -
Prince#inputs(filename): Prince: set one (in casefilenameis a string) or multiple (in casefilenameis an array of strings) input XML/HTML files. This returns the Prince API for further method chaining. -
Prince#output(filename): Prince: set the output PDF file. This returns the Prince API for further method chaining. This is optional if the PrinceXML optionraster-outputis given. -
Prince#option(name, value[, forced]): Prince: set a PrinceXML option namenameto a valuevalue. The API knows the officially supported options of PrinceXML 9.0 and by default rejects unknown options. But arbitrary options can be passed by settingforcedtotruein case a different PrinceXML version should be used. This returns the Prince API for further method chaining. -
Prince#execute(): Promise: asynchronously execute the conversion process. This returns a promise. On success it resolves to an object withstdoutandstderrfields. On error, it resolves to an object witherror,stdoutandstderrfields.
