Managing Digital Assistant node dependencies
Digital Assistant uses global and local npm modules, which allows to efficiently manage dependencies.
To use npm, you need to have Node.js installed locally on your server.
There's a small number of dependencies that are used throughout Digital Assistant, therefore we made them globally accessible. These modules are:
- agentkeepalive - The Node.js's missing
- cookie - Basic HTTP cookie parser and serializer for HTTP servers
- got - Simplified HTTP requests
- mssql - Microsoft SQL Server client for Node.js
require statement e.g.
let got = require('got');
