VisualizaçõesAngular Material (8) S2591: Cannot find name 'require'
I am trying to log date/time into the javascript console. The error message I am getting is as follows and was generated by the code below.
ETA: the code does work. The dates are going to the console. It is just the Error Message remains
Message:
ERROR in src/app/kdc/services/customers.api.service.ts(60,9): error TS2591: Cannot find name 'require'. Do you need to install type definitions for node? Try
npm i @types/nodeand then addnodeto the types field in your tsconfig.
NOTE: I have already made changes to the tsconfig.json file and have also done npm i @types/node and npm i @types/node --save When running npm result was 3 high-security vulnerabilities (see below)
What can I do at this point?`
customer.api.service.ts
getCustomers(): Observable<Customers[]> {
return this.httpclient.get<Customers[]>(this._url)
.pipe( catchError(this.handleError));
}
handleError(error:HttpErrorResponse){
let rval = Math.random().toString(36).substring(7).toUpperCase();
require('log-timestamp');
console.error('MSG NO :' + rval );
console.error(error);
return throwError(rval + " <-> " + error.name + " <-> " + error.statusText );
}
ETA
I found the message here Cannot find name 'require' after upgrading to Angular4 and made the change to my
tsconfig.app.json file - it may be overkill, but it worked ...
"compilerOptions": {
"outDir": "./out-tsc/app",
"types": [ "node" ],
"typeRoots": [ "../node_modules/@types" ]
},

Make sure you put the type in your tsconfig.app.json not your tsconfig.json
"compilerOptions": {
"module": "esNext",
"types": ["node"]
},
Also make sure your systax in your component look like this
const someLib = require("someLib"); // make sure the name is match with your package name
Then stop angular cli then run again

Nowadays you can use ECMAScript import. From
const someLib = require("someLib");
to
import * as someLib from 'someLib';
