Node.js examples

Working Node.js examples for the ThumbAPI generate endpoint.

Setup

# Requires Node.js 18+ (built-in fetch). Tested on Node 20 and 22.
export THUMBAPI_KEY="your_api_key_here"

Get an API key at app.thumbapi.dev — free tier is 5 generations/month, no credit card required.

basic-generate.js — minimal POST request, save the WebP to disk.
with-personal-image.js — with-image style: include a person's face from a local JPEG.
batch-from-csv.js — read titles from a CSV, generate one thumbnail per row with retry + concurrency control.

node basic-generate.js
node with-personal-image.js
