Problem when requiring module in ionic framework

Question

In my project (using the ionic-framework 3) I have used following statement to require the dialogflow module:

const dialogflow = require('dialogflow');

On compilation it's throwing the following error:

cannot find name 'require'.

How can I resolve this?

Answer 1

Add types to tsconfig.json

"types": [
    "node"
],
"typeRoots": [
    "node_modules/@types"
]
