🚪 Borrow Limiter

Self-hostable rate limiting API for protecting regular service usage.

Usage

Let's use the fixed window algorithm to rate limit our login endpoint to 10 requests per minute.

import { limiter } from "@borrowdev/limiter";

const { success, timeLeft } = await limiter(
  {
    key: "my-limiter-id",
    userId: "current-user-id",
  },
  {
    limiters: [
      {
        maxRequests: 10,
        interval: "minute",
        type: "fixed",
      },
    ],
  },
);
if (!success) {
  return {
    message:
      "Rate limit exceeded." + timeLeft !== null
        ? ` You can try again in ${timeLeft} seconds.`
        : "",
  };
}

Self-host

🛠 Borrow CLI

Install

cargo install borrow-dev

Borrow Start

Borrow Start is a command-line tool that helps you quickly set up common boilerplate code with pre-defined templates and placeholders.

Templates are downloaded from the Borrow registry, or you can create your own templates and refer to them locally by using the local: prefix before <template>.

Usage

# Download and install a template
borrow start new -t <template> -o <output_dir>
# Delete a template from the cache
borrow start del -t <template>

Example

borrow start new -t supabase-proxy -o ~/my-awesome-project

Roadmap

• Add support for self-hosted GitHub templates.
• Add support for package metadata.
• Add support for sandboxed template code execution with hooks.
• Add support for per-file config with frontmatter.
• Write documentation for how to create your own templates.
