JSLink URL Tokens in SharePoint

Following are some of the JSLink URL Tokens I have come across in SharePoint.

  • ~site – reference to the current SharePoint site (or “Web”)
  • ~sitecollection – reference to the current SharePoint site collection (or “Site”)
  • ~layouts – version specific reference to the web application Layouts folder (so it will automatically swap out /_layouts/14 or /_layouts/15 for you)
  • ~sitecollectionlayouts – reference to the layouts folder in the current site collection (e.g. /sites/team/_layouts/15)
  • ~sitelayouts – reference to the layouts folder in the current site (e.g. /sites/teams/subsite/_layouts/15)

Few Examples:

Setting up Node.js & NPM on a machine without administrative privileges and behind a corporate proxy

Recently I was trying to setup a development machine at our office and realized few issues.

  1. The machine didn’t have administrative privileges
  2. It was located behind the corporate proxy
  3. It uses Windows 10 as primary OS

So how to proceed? Following is what I did.

[Update: Now node.js includes npm, so I would suggest to download only node.]

Downloading Node.js & NPM

  1. Download the Node.js binary instead of installer from the below URLs

Node.js binary (32bit or 64 bit):

  1. Download NPM binary release from the url below

NPM Release:

  1. Extract Node.js to D:\Development\Node
  2. Extract NPM to D:\Development\NPM

Set up environment

Every time the development environment is booted do the following

  1. Start a command prompt and set the following path

  1. Check the Node version by typing the following

  1. Check the NPM version by typing the following

If you get version numbers for both then both are working.

  1. Now set proxy so that NPM can download modules by running the following

Now the environment is set up.
Do remember, once the console is closed, all the above settings are lost and needs to be run again, just follow the section “Set up environment” again or do the following.

You can set up the “path” variable without administrator privileges in Windows by doing the following.

  1. From Windows’s Start Menu, open Control Panel.
  2. In Control Panel open “User Accounts”.
  3. In ‘User Accounts” open “Change my environment variables”.
  4. This will open the user’s “Environment Variables” window.
  5. Select the row with entry “Path”.
  6. Click “Edit” button.
  7. In the “Variable value:” text box, append the path of your executable location, which in this case is “D:\Development\Node;D:\Development\Node\node_modules\npm\bin;
  8. Click OK
  9. Open a new terminal or console
  10. Type “node -v” to check if node is working fine.
  11. type “npm -v” to check if npm is working fine.

Samsung Pay

Samsung Pay – It’s easy and fast !

Samsung Pay is now available in India and I am delighted !

Samsung Pay

Pre March 2017…..

In India transactions at shops happen in three ways generally.

  1. Pay in cash
  2. Swipe your debit or credit card and pay
  3. Use digital wallets like Paytm

Issues one might face with cash is, unavailability of proper change or too much of cash in the wallet leading to larger wallets getting either pick pocketed or when most of the people keep it in their back pockets it has impact on your spinal cord.

With debit or credit cards, the magnetic strip wears off after repeated usage or lost. Replacement of cards are generally charged.

Using digital wallets requires an amount to be stored in their account and some times it’s an issue when some out lets don’t support them.


I pay mostly using digital mode until unless the total bill is less than ₹100.00

Following were some of the the issue which I faced.

  1. Wear and tear of debit card or the machine
  2. I leave my wallet at home
  3. QR code at shop is worn off and my banking app doesn’t recognize it

Especially after demonetization resulting in crash crunch, people started to use digital mode of payment more frequently which resulted in POS machines wearing off more frequently.

Post March 2017…..

Samsung launches Samsung Pay in India with almost all the Indian banks being supported.
Initially I was little hesitant, but then decided to try for one particular reason of it being supporting the magnetic readers based machine too as opposed to NFC only. Following is what I did,

  1. Update the Samsung Pay to latest
  2. Register my debit card and agreed for virtual card to be created
  3. Confirm addition of card via OTP

Now my mobile has a digital card added to it’s lock, home screen.

I went out for a purchase and when I was supposed to pay the bill the shop keeper requested me to handover the debit or credit card. I told him I will pay via mobile and he was little confused.

  1. So I got the POS Swipe machine from him
  2. Pressed the power button in my mobile to show the lock screen
  3. Swipe up the Samsung Pay app
  4. Choose the debit card
  5. Keep the mobile near the magnetic reader of the swipe machine
  6. Then payment was same as swiping the card
    1. Enter amount
    2. Enter pin
    3. Payment approved slip being printed out

Samsung Pay Process

It was very easy.

Following are some of the advantages of Samsung Pay

  1. It supports both NFC based and magnetic based readers, hence more POS machines are supported
  2. Samsung’s KNOX (a secure storage space inside mobile) stores the information about the virtual card
  3. I guess Apple supports only NFC and hence less number of POS machines supported
  4. Also Apple and native Android has lower number of banking support in India

The interesting part is people around you are shocked to see such a payment system is available in India !

Sync desktop files to O365 SharePoint Library

One of the consulting request I got was that an user should be able to sync files from a legacy system to O365 SharePoint Library. The issue was that the legacy system was old and all it could do was place a file in a particular folder.

The solution we could offer was the following.

  1. Configure a Windows mapped drive to point to a SharePoint library
  2. Configure the legacy system to place file into folder

This worked, but having a mapped drive was received as a security threat by the client’s security team.

But now thanks to the newly launched feature of syncing the SharePoint library files with OneDrive, this is easier.
Best part is, it supports both Windows & Mac.
