This tutorial teaches FIWARE users how to alter the context programmatically. The tutorial builds on the entities

created in the previous [stock management example](https://github.com/FIWARE/tutorials.Context-Providers/) and enables a

user understand how to write code in an [NGSI-v2](https://fiware.github.io/specifications/OpenAPI/ngsiv2) capable

[Node.js](https://nodejs.org/) [Express](https://expressjs.com/) application in order to retrieve and alter context

data. This removes the need to use the command-line to invoke cUrl commands.

The tutorial is mainly concerned with discussing code written in Node.js, however some of the results can be checked by

making [cUrl](https://ec.haxx.se/) commands.

# Start-Up

**NGSI-v2** offers JSON based interoperability used in individual Smart Systems. To run this tutorial with **NGSI-v2**, use the `NGSI-v2` branch.

```console

cd tutorials.Accessing-Context

git checkout NGSI-v2

./services create
