Liquid
The templating language used by Power Pages for rendering content — variables, tags, filters with safe sandboxed evaluation.
Liquid is the templating language originally created by Shopify, now used by Power Pages for rendering portal content. Liquid mixes HTML with outputs ({{ variable }} for printing values), tags ({% if %}, {% for %}, {% capture %} for control flow), and filters (| upcase, | date, | escape for transformations). Power Pages exposes specific objects — user, page, entities, weblinks, request — for accessing live data. Templates query Dataverse through {% fetchxml %} and {% entityview %} tags. Logic is intentionally limited — sandboxed, no arbitrary code execution — for safe content rendering of customer-facing pages. Auto-escapes user-supplied content to prevent XSS; bypassing escaping is rarely the right choice.
