go-validation

Validation Plugin

A Lesstruct plugin that validates content before it is saved by rejecting empty titles.

Prerequisites

• TinyGo 0.28+

Build

tinygo build -o validation.wasm -target=wasi main.go

Install

Copy the compiled WASM file to the Lesstruct plugins directory:

cp validation.wasm <lesstruct-project>/plugins/

Expected Behavior

When content is saved, the plugin intercepts the before_save hook and checks if the "title" field is empty.

• If the title is empty, the plugin returns an error response:

  {"error":"validation failed","message":"title must not be empty"}
  

• If the title is not empty, the original content passes through unchanged.
