• spBaseFolder - base folder path which is omitted then saving files locally [string, optional, default: equals to spRootFolder]
• recursive - to pull all files and folders recursively [boolean, optional, default: true]

Overloads / cases

• All files with folder structure from spRootFolder
• Files from spRootFolder folder, first hierarchy level only
• Folders structure from spRootFolder without files
• Files based on array of paths provided strictly [works with array of files only right now]
• Files based on CAML query conditions
• Pull for documents metadata to use it in callback's custom logic

Use case scenarios can be found on the Scenarios page. This page suggests combinations of options which are optimal for certain use cases.

successHandler

Callback gets called upon successful files download.

errorHandler

Callback gets executed in case of exception inside sppull. Accepts error object as first argument for callback.

Samples

Refer to the Scenarios page for suggested options combinations available with sppull.

Basic usage

TypeSctipt:

import { AuthConfig as SPAuthConfigurator } from 'node-sp-auth-config';
import SPPull, { ISPPullOptions, ISPPullContext } from 'sppull';

new SPAuthConfigurator().getContext().then(({ siteUrl, authOptions }) => {

  const context: ISPPullContext = {
    siteUrl: context.siteUrl,
    ...context.authOptions
  } as any;

  const options: ISPPullOptions = {
    spRootFolder: 'Shared%20Documents',
    dlRootFolder: './Downloads/Documents'
  };

  SPPull.download(context, options);

}).catch(console.log);

or ES6:

const { SPPull } = require('sppull');

const context = {
  siteUrl: "http://contoso.sharepoint.com/subsite",
  creds: {
    username: "user@contoso.com",
    password: "_Password_",
    online: true
  }
};

const options = {
  spRootFolder: "Shared%20Documents/Contracts",
  dlRootFolder: "./Downloads/Contracts"
};

/*
 * All files will be downloaded from http://contoso.sharepoint.com/subsite/Shared%20Documents/Contracts folder
 * to __dirname + /Downloads/Contracts folder.
 * Folders structure will remain original as it is in SharePoint's target folder.
*/
SPPull.download(context, options)
  .then((downloadResults) => {
    console.log("Files are downloaded");
    console.log("For more, please check the results", JSON.stringify(downloadResults));
  })
  .catch((err) => {
    console.log("Core error has happened", err);
  });

Passwords storage

To eliminate any local password storing if preferable to use any two-way hashing technique, like cpass.

Inspiration and references

This project was inspired by spsave by Sergei Sergeev and gulp-spsync by Wictor Wilén projects.

SPPull depends heavily on sp-request module and use it to send REST queries to SharePoint.
