Serverless function execution platform

Lambda runs JavaScript functions and static assets behind HTTP endpoints on HolaCloud.

Get started Documentation

Lambda

Key features

Create, update, list, delete, and invoke HTTP functions through the Lambda API.

JavaScript functions

Run JavaScript with the built-in runtime helpers such as write, body, query, and headers.

HTTP invocation

Invoke functions through public run URLs, authenticated admin run URLs, or owner/project mux routing.

Static responses

Serve static HTML, CSS, and JavaScript snippets with the same Lambda model.

Quick start

Get started with Lambda in seconds using the API.

curl -X POST https://api.hola.cloud/api/v0/lambdas \
  -H 'X-Glue-Authentication: {"user":{"id":"user-123"}}' \
  -d '{"name":"hello","language":"javascript","method":"GET","path":"/hello","code":"write(\"Hello from Lambda\")"}'

POST /api/v0/lambdas HTTP/1.1
Host: api.hola.cloud
X-Glue-Authentication: {"user":{"id":"user-123"}}

{"name":"hello","language":"javascript","method":"GET","path":"/hello","code":"write(\"Hello from Lambda\")"}
