I am trying to do base64 encode in NodeJS using TypeScript.
When I am writing same thing in TypeScript and compiling, I am getting Buffer is not find error.
var base64Policy = new Buffer(stringPolicy, 'utf-8').toString('base64');
Can someone help me to do same thing in TypeScript.
Add this line at top:
declare const Buffer
and it should compile without errors.

With new version of Typescript, you can also use official declaration files:
npm i -g typescript@next
npm i --save-dev @types/node
for other libraries, install
