mirri-link

CLI and TypeScript library for uploading files to mirri.link.

Install

# As a CLI
npm install -g mirri-link

# As a library
npm install mirri-link

CLI

The CLI is exposed as mirri. It prints the resulting public URL to stdout.

Upload a file

mirri ./report.pdf
# → https://mirri.link/abc123

Upload from stdin

echo "hello world" | mirri
# Uses default filename "file.txt" and content-type "text/plain"

echo "# Hello" | mirri --filename hello.md
# Markdown is rendered to a styled HTML page

cat data.json | mirri -f data.json -t application/json

Options

Flag	Default	Description
-f, --filename <name>	basename of path, or file.txt for stdin	Filename to upload as
-t, --content-type <t>	guessed from filename, or text/plain for stdin	MIME type
-e, --expiry <dur>	(no expiry)	Expire after duration (e.g. 30s, 5m, 2h, 2d, 1w, 1y)
-h, --help		Show help

mirri ./screenshot.png --expiry 2d
cat data.json | mirri -f data.json -t application/json -e 1h

Markdown handling

Any upload whose content-type is text/markdown (including any .md or .markdown file) is routed through mirri.link's markdown API, which renders the content to a styled HTML page rather than serving the raw source. Expiry is not supported for markdown uploads.

Library

import { uploadFile, upload, uploadMarkdown, parseDuration } from 'mirri-link'

// Upload a file from disk
const { publicUrl } = await uploadFile('./image.png')

// Upload a file that expires in 2 days
await uploadFile('./report.pdf', { expiry: parseDuration('2d') })

// Upload a buffer or string with explicit metadata
const result = await upload(Buffer.from('hello'), {
  filename: 'greeting.txt',
  contentType: 'text/plain',
})

// Upload markdown content directly (returns a rendered HTML page)
const md = await uploadMarkdown('# Hello\n\nThis is a test.')

API

uploadFile(path, options?)

Reads a file from disk and uploads it. The filename and content-type are inferred from the path unless overridden. Accepts optional expiry (seconds).

upload(body, options)

Uploads a Buffer, Uint8Array, ArrayBuffer, or string with explicit filename and contentType. Accepts optional expiry (seconds). Automatically routes through the markdown API when contentType is text/markdown.

parseDuration(input)

Parses a duration string like "30s", "5m", "2h", "2d", "1w" (or a bare number of seconds) into a number of seconds. Useful for converting human-friendly input into the expiry option.

uploadMarkdown(content)

Posts markdown content to mirri.link's markdown API and returns a URL to a rendered HTML page.

All upload functions return Promise<{ publicUrl: string }>.
