Javascript Sandbox Tutorial =========================== This is a javascript sandbox tutorial for writing standalone Javascript sandbox applications (that connect to Junebug) too. What is the sandbox? -------------------- A sandbox is an isolated execution environment, but its used in production, not testing, and its role is to provide access to carefully selected external resources and capabilities (e.g. logging, web requests, a key-value store, sending messages).

Outcomes of the tutorial ------------------------ By the end of this tutorial, you will be able to: - Understand the structure of a sandbox application repository - Write a sandbox application - Write tests - Know how to make an HTTP request from a sandbox application - Translate your application into other languages - Work with promises - Deploy your application to Vumi Go Other documentation ------------------- .. toctree:: :maxdepth: 1 sandbox_skeleton.rst deploying_to_VumiGo.rst creating_states.rst updating_tests.rst add_an_http_request.rst
