Integrating GroupDocs.Annotation Cloud SDK into your Node.js applications is very easy. No installation is required on the server or client side. Just create an account at GroupDocs.Cloud to get App SID & key. Following example shows how easy it is to import annotation information using Node.js:
// load the module
var GroupDocs = require('groupdocs-annotation-cloud');
// get your appSid and appKey at https://dashboard.groupdocs.cloud (free registration is required).
var appSid = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";
var appKey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
// construct AnnotationApi
var infoApi = GroupDocs.InfoApi.fromKeys(appSid, appKey);
// retrieve supported file-formats
infoApi.getSupportedFileFormats()
.then(function (response) {
console.log("Supported file-formats:")
response.formats.forEach(function (format) {
console.log(format.fileFormat + " (" + format.extension + ")");
});
})
.catch(function (error) {
console.log("Error: " + error.message)
});
Using GroupDocs.Annotation Cloud SDK for Node.js, you can work with diverse types of annotations. The two basic types are; Text Annotations and Figure Annotations. While using text-based annotation, you can add text comments to selected text; highlight which text should be replaced with what, hide confidential text using text redaction, highlight text with strikethroughs/underlines, and add sticky notes with rich text. While working with figure annotations, you can add notes to an area highlighted with a rectangle (Area Annotation), add notes to any point in the document (Point Annotation), hide confidential parts of an image or text (Area Redaction), draw freehand lines and shapes (Polyline), arrows pointing to an object (Pointer/Arrow), create text-based watermark overlays (Watermark), and measure the distance between any objects in a document (Distance Annotation).
