使用ES6导入节点模块时找不到模块的声明文件

Question

I have setup loopback 4 and trying to write a new controller for my Braintree API payments. I have installed the Braintree npm module and using

import {braintree} from 'braintree';

to import into a controller and use in an endpoint. But it is throwing me following error:

*src/controllers/braintree.controller.ts:23:25 - error TS7016: Could not find a declaration file for module 'braintree'. '/home/oem/Learning/learn-loopback/my-todo-app/node_modules/braintree/index.js' implicitly has an 'any' type.
Try `npm install @types/braintree` if it exists or add a new declaration (.d.ts) file containing `declare module 'braintree';*`

When I try the es5 way of importing it is working fine.

Not sure how to fix this.

Answer 1

The braintree type does not seem to exist yet. So here you have 2 possibilities:

• You create a type file as suggested in the error, but you need to have a good knowledge of the braintree library.
• Replace import {braintree} from 'braintree'; with const braintree = require('braintree'); but you won't have access to all the typescript magic, so be careful when manipulating this library.
