How to work properly with the request?

Question

I need to send a simple notification using onesignal, but is giving error in the build of the web app because of https import, as the code I am importing as follows:

var https = require('https');

Note: This example is from the site of onesignal itself, the problem is that I can not do the request otherwise, so it works, but at the time of the build error. So what I need to basically do is, figure out another way to call this https to request the onesignal api and solve the problem. That’s all I need to close this project.

  notificaAgendamentoCriadoProfissional(){
  var sendNotification = function(data) {
  var headers = {
    "Content-Type": "application/json; charset=utf-8"
  };

  var options = {
    host: "onesignal.com",
    port: 443,
    path: "/api/v1/notifications",
    method: "POST",
    headers: headers
  };

  var https = require('https');
  var req = https.request(options, function(res) {  
    res.on('data', function(data) {
      console.log("Response:");
      console.log(JSON.parse(data));
    });
  });

  req.on('error', function(e) {
    console.log("ERROR:");
    console.log(e);
  });

  req.write(JSON.stringify(data));
  req.end();
};

var message = { 
  app_id: "meu id",
  contents: {"en": "Você recebeu uma nova solicitação. Verifique imediatamente a sua lista de agendamentos"},
  include_player_ids: [this.idOneSignalProfissional]
};

sendNotification(message);

}

The mistake I’m getting is always this:

[18:23:19]  typescript: ...roAdm/src/pages/criar-agendamento-procedimento/criar-agendamento-procedimento.ts, line: 178 
        Cannot find name 'require'.

L178:   var https = require('https');

Here’s an example of how I solved this question:

  notificaAgendamentoCriadoProfissional() {
  let data = {
  app_id: "Seu Id do onesignal",
  contents: { "en": "Você recebeu uma nova solicitação. Verifique imediatamente a sua lista de agendamentos" },
  include_player_ids: ['id do usuário do one signal']
};
let url = 'https://onesignal.com/api/v1/notifications';
let headers = new HttpHeaders({
  "Content-Type": "application/json;charset=utf-8"
});

this.http.post(url, data, { headers: headers })
  .subscribe((result: any) => {
    console.log('sucesso ao salvar');
    console.log(result);
  },
    (error) => {
      console.log(error);
    });

}
