Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@onveloz/blob

v0.1.1-beta.1

Published

SDK oficial do Veloz Blob — uploads, downloads e delete via CDN.

Readme

@onveloz/blob

SDK oficial do Veloz Blob — envie, sirva e remova arquivos por uma CDN global.

Cada blob store recebe um domínio dedicado (ex.: meu-app.cdn.runveloz.com) e você envia objetos a partir do seu app com este SDK ou direto pela API REST.

Instalação

npm install @onveloz/blob

Requer Node 18+ (ou qualquer runtime com fetch global). Em ambientes sem fetch, passe { fetch } em cada chamada.

Autenticação

Toda chamada usa uma chave vbk_* vinculada a um blob store, gerada na aba Chaves de API do store no dashboard. Defina no ambiente:

VELOZ_BLOB_TOKEN=vbk_sua_chave

Trate a chave como senha: nunca commite no Git. Para apontar para outro ambiente, defina VELOZ_BLOB_API ou passe apiUrl em cada chamada.

Uso

import { put, del } from "@onveloz/blob";

// Lê VELOZ_BLOB_TOKEN do ambiente (ou passe { token }).
const blob = await put("uploads/foto.png", arquivo, {
  access: "public",
  contentType: "image/png",
});

console.log(blob.url); // https://meu-app.cdn.runveloz.com/uploads/foto.png

await del("uploads/foto.png");

put aceita string, Blob, ArrayBuffer, ArrayBufferView, Uint8Array ou ReadableStream como corpo.

Cliente com configuração fixa

import { BlobClient } from "@onveloz/blob";

const blob = new BlobClient({ token: process.env.VELOZ_BLOB_TOKEN });
await blob.put("uploads/foto.png", arquivo);
await blob.del("uploads/foto.png");

Erros

O SDK lança erros tipados:

| Erro | Quando | | ----------------- | ------------------------------------------ | | BlobAccessError | token ausente ou inválido (401/403) | | BlobUploadError | falha no envio do arquivo à CDN | | BlobError | genérico, com code e status (ex.: 429) |

Como funciona

O envio é em dois passos, transparente para quem usa o SDK:

  1. POST /api/blob/v1/upload-url troca a sua chave por uma URL de upload assinada e temporária.
  2. PUT direto nessa URL — o payload é encaminhado ao armazenamento via CDN.

A chave vbk_* só trafega no cabeçalho Authorization, nunca na URL.
