Getting error TS2304: Cannot find name 'Buffer'
Add this line at top:
declare const Buffer
and it should compile without errors.
Declarations is required to use node built in libraries or other global objects, you can manually declare it like above.
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 @types/library_name
.

For the IONIC 4 developers, I installed it usingnpm install --save @types/node
When I tried adding "types": ["node"]
as shown below
"compilerOptions": {
"outDir": "./out-tsc/app",
"types": ["node"]
},
to the tsconfig.json
it did not work. I had to add the entry totsconfig.app.json
