I'm facing an issue while trying to utilize Buffer in my angular component ts for encoding the Authorization string.
Even after attempting npm i @types/node and adding "node" to types field in tsconfig.json, it still doesn't compile with ng build.
The error details are as follows:
ERROR in src/app/register/register.component.ts(40,29): error TS2591: Cannot find name 'Buffer'. Do you need to install type definitions for node? Try `npm i @types/node` and then add `node` to the types field in your tsconfig.
This is the code snippet from register.component.ts
import { Component, OnInit } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { User, PricingPlan } from 'api';
import * as EmailValidator from 'email-validator';
@Component({
selector: 'app-register',
templateUrl: './register.component.html',
styleUrls: ['./register.component.scss']
})
export class RegisterComponent implements OnInit {
model = new User();
passwordRepeat = '';
pricingPlans: PricingPlan[];
userExist = false;
serverUrl = 'http://127.0.0.1:3000/';
registerSuccess = false;
registerFailed = false;
constructor(private http: HttpClient) {}
ngOnInit() {
this.http
.get(`${this.serverUrl}pricingplans`)
.subscribe((pricingplans: PricingPlan[]) => {
this.pricingPlans = pricingplans;
});
}
validateEmail(em) {
return EmailValidator.validate(em);
}
validatePasswords() {
return this.passwordRepeat === this.model.password;
}
save() {
const auth = 'Basic ' + Buffer.from(this.model.email).toString('base64');
this.http.get(`${this.serverUrl}user`, {
headers: {
Authorization: auth
}
}).subscribe((responce: User) => {
this.userExist = (responce.email === this.model.email);
});
if (this.userExist) {
return;
}
}
}
This is my current tsconfig.json configuration
