It provides access to the HDI-, Container-Group- and the Container-API.\n\n## Table of contents\n **Using the library**:\n- [General things](#general-things)\n- [Using the HDI API](#using-the-hdi-api)\n- [Using the Container Group API](#using-the-container-group-api)\n- [Using the Container API](#using-the-container-api)\n- [Using the API with xsjs](#using-the-api-with-xsjs)\n\n## General things\n\nAssuming that your **npm registry** is correctly configured and has access to SAP packages, simply running `npm install --save @sap/hdi` will install the package and add it as a dependency to your **package.json**.\n\nWe recommend using version 2.0.0 or higher. V2 of the API brings access to the Container Group API, major refactoring of the HDI and Container API into separate components and lots of pre-defined classes to make working with the API easier.\n\nNote that V2 is not backwards compatible to V1, code written with the old API will ***NOT*** run with new API. This documentation is for the V2 API.\n\nAll APIs require that the connected user has EXECUTE privileges for the corresponding SQL procedures and SELECT for all table types in SYS_DI (TT*).\n\nAlmost all methods are asynchronous and require a standard node-style callback, where the first parameter is any errors that occured and the second is the result.\n\n**This document only provides a really high-level and shallow overview of the API. For a more detailed, technical documentation, refer to the JSDoc. To generate the documentation, run `npm install jsdoc`,`npm install ink-docstrap` and then `npm run documentation`. The documentation can then be found in the `docs` folder.**\n\n\n## Using the HDI API\nAccess to the _SYS_DI API is provided by the `HDI` class. Access to this API requires HANA server version: 1.00.120 or newer. To work with the API, simply construct a new object, as can be seen in the following (ES6-based) example:\n\n```javascript\nconst { HDI } = require('@sap/hdi');\n\n#This credentials object will be directly passed to the hdb client. Any options accepted by the hdb client can be passed.\nconst credentials = {\n host : <host>,\n port : <port>,\n user : <user>,\n password: <password>\n};\n\nconst hdi = new HDI(credentials, parameterSchema);\n\nhdi.connect((error,result) => {\n if(error){\n throw error;\n }\n\n hdi.listLibraries(null,(error,result) => {\n if(error){\n throw error;\n }\n\n console.log(result);\n })\n})\n```\n\nTo construct an access object, you need the credentials for the HANA system and the `parameterSchema`. This schema will be used to create temporary tables to supply data to the underlying sql procedures.\n\n## Using the Container Group API\nThe Container Group API provides access to an **existing** container group. In order to use the API, you might need to first grant the correct rights by using `grantContainerGroupAPIPrivileges` of the HDI class.\n\nTo construct an access object, you need the credentials for the HANA system, the `parameterSchema` and the name of the container group.\n\n## Using the Container API\nThe Container API provides access to an **existing** container. In order to use the API, you might need to first grant the correct rights by using `grantContainerAPIPrivileges` of the ContainerGroup class.\n\nTo construct an access object, you need the credentials for the HANA system, the `parameterSchema` and the name of the container.\n\nExample: Deploying files to a container\n\n```javascript\n'use strict';\n\nconst fs = require('fs');\nconst async = require('async');\nconst path = require('path');\n\nconst {Container, HDI, FileWithContent, FolderWithContent, File, Parameter} = require('@sap/hdi');\n\n// This credentials object will be directly passed to the hdb client.

This fixes issues with `sync` in combination with class methods.\n\nIf your version of xsjs is up to date in that regard, simply add `sync` before your method calls.

Almost all methods are asynchronous and require a standard node-style callback, where the first parameter is any errors that occurred and the second is the result. Keep in mind that the error-parameter is only supplied when a "technical" error occurs. To check if the action was succesful, you need to check the return code (rc) of the returned result.
In order to "automate" this, for example when chaining multiple calls with async where you want to exit when one of the calls encounters a "non-technical" error, you can wrap your callback with the function below:
```javascript
function wrap (callback) {
return function (error, result) {
if (error) {
return callback(error);
} else {
if (result.rc && result.rc !== 0) {
const e = new Error('HDI call failed!')
e.result = result
return callback(e, result);
} else {
return callback(null, result);
}
}
}
}
