    Use Twilio Video to Create a Dog Camera Dog Cam

    There are multiple apps and services out there that you can use as a dog cam. However, most of these apps and services require you to pay for new devices or a subscription (or both!). When I recently adopted a puppy, I used Twilio Video and an old phone to create my own free dog cam.

    In this blog post, I’ll show you how to build your own dog cam using:

    1. a Twilio account – sign up for free
    2. Python 3.x
    3. the micro web framework Flask
    4. the Twilio Python helper library
    5. ngrok - sign up for free
    6. An old phone or tablet


    For the Dog Cam, there were a few features I wanted:

    Free or low cost solution

    Existing dog cameras mostly require you to spend money on a subscription or new hardware. What I wanted was a free or low cost solution that can run on any internet-connected …

    Receiving Emails with Node.js, Express, and Twilio SendGrid's Inbound Parse Copy of C04 Blog Text (3).png

    Setting up an application to receive emails can be tiresome if you want to do it yourself. Luckily Twilio SendGrid includes the Inbound Parse feature, a greatly simplified method for receiving emails based on webhooks. Let's walk through how to receive emails on your own domain using Node.js.

    Requirements and dependencies

    We'll need to install the node modules for Express and the multer middleware. To install these npm modules, navigate to the directory where you want this code to live and run the following command in your terminal to create an npm package for this project:

    npm init --yes

    The --yes argument just runs through all of the prompts that you would otherwise have to fill out or skip. Now that we have a package.json for our app, let’s install the necessary libraries with the following shell command:

    npm install express@4.17.2 multer@1.4.4

    Domain authentication

    The first step in setting up …

    Send Scheduled SMS with Node.js and Twilio Send Scheduled SMS with Node.js and Twilio

    Twilio is all about powering communication – and doing it conveniently and fast. Our Programmable Messaging service has been available for a long time, but until now, scheduling a message to be sent at a future time required a developer to use their own scheduling solution.

    Fortunately, this is now a thing of the past! With Message Scheduling, you can send your scheduled SMS and MMS messages with a single API call, without using custom schedulers.

    In this tutorial, you’ll learn how to send scheduled SMS notifications in a Node.js application.

    Como proteger URLs do webhook Twilio em Node.js Como proteger URLs do webhook Twilio em Node.js

    As APIs da Twilio permitem que os desenvolvedores reinventem as comunicações com recursos como chamadas telefônicas, SMS ou chatbots inteligentes programáveis. Os desenvolvedores podem criar aplicativos para interagir com seus usuários e reagir às respostas deles. Para responder a eventos como mensagens recebidas, você pode definir um URL de webhook. Um webhook é uma solicitação HTTP que a Twilio executa para descobrir qual deve ser a reação a um evento da Twilio, como um SMS recebido. Seus endpoints HTTP definidos precisam responder com uma linguagem de configuração Twilio compreensível chamada TwiML (Twilio Markup Language).

    Esses endpoints podem ser hospedados em qualquer lugar, desde que estejam disponíveis publicamente e acessíveis pela infraestrutura da Twilio.

    Três formas de proteger os URLs do seu webhook

    Vamos supor que você tenha criado um aplicativo de classificação que permita aos usuários classificarem um evento no qual estão enviando um SMS para um determinado …

    Como criar uma campo de número de telefone internacional em HTML e JavaScript Como criar uma campo de  telefone internacional em HTML e JavaScript

    Os números de telefone são padronizados em um formato internacional conhecido como E.164, que combina códigos do país e números de assinante em um formato como este: +14155552671. Esse formato é exigido por muitas APIs (incluindo a da Twilio) e significa que você não precisa armazenar códigos de países e números de telefone em duas colunas de banco de dados separadas.

    No entanto, você provavelmente não quer que seus usuários tenham que digitar um sinal de mais (+) e o código do país ao informar o número de telefone para:

    • registrar uma nova conta
    • ativar a autenticação 2FA para SMS
    • solicitar um retorno de chamada do atendimento ao cliente
    • inscrever-se para receber notificações de marketing

    Este post mostrará como criar um campo de entrada de número de telefone para processar e analisar números de telefone usando HTML básico, JavaScript e o plugin intl-tel-input. Incluiremos recomendações para verificação …

    What’s Svelte?

    Svelte is an open-source front-end framework for creating interactive user interfaces that run in a browser.

    Differences with React and Vue.js

    However, there is a crucial difference between Svelte and React or Vue.js. Svelte doesn’t use virtual DOM. Svelte is a compiler written in TypeScript that compiles JavaScript at build time, whereas React and …
