HandlebarsisthenameofaJavaScriptlibrarythatimplementsatemplatinglanguage(see
https://handlebarsjs.com/).Itusesatemplateandaninputobjecttogenerateoutput.
ThetemplatelookslikeregulartextwithembeddedHandlebarsexpressions.Ahandlebarsexpression
issomecontentsenclosedbydoublecurlybraces:{{...}}.Forexample:
<p>Hello {{firstname}}!</p>
Whenthetemplateisrendered,theseexpressionsarereplacedwithvaluesfromaninputobject.
TheHandlebarslibraryisintegratedinOLConnectDesigner.ThismeansthatyoucanuseHandle-
barsexpressionsinallsections(asofversion2022.2),aswellasinaspecialtypeofsnippetscalled
"Handlebarstemplates"(asofversion2022.1).
ThebigadvantageofusingHandlebarssnippetsinOLConnectisthatonlyoneortwoverysimple
Designerscriptsareneededtoreplaceapotentiallylargenumberofexpressionswithvaluesandinsert
thecontentinasection.ThisisespeciallybeneficialforOLConnecttemplateswithmanysnippetsand
variabledatathatwouldotherwiserequirealargenumberofscripts.
WorkingwithHandlebarstemplatesinvolvesalittlebitofscripting.Ifyouarenewtoscriptinginthe
Designer,firstread:"Writingyourownscripts"onpage808.

notnecessarilyvalidHTML.ProcessingitwithanHTMLparsermightbreakboththeHandlebars
expressionsandtheHTML.
