Racle météo

This service cleverly transforms weather web pages into a usable (and free!) rest API. It uses accuweather and/or foreca under the hood.

• Sturdy: Uses other providers as fallback to guarentee a response if a provider becomes invalid
• Flexible: Easy to update with strong typing and htmlparser2 as basic parser
• Compatible: Pure typescript using deno and small dependencies means you can install it almost anywhere

Install

Deploy a Cloudflare Worker to start using your own racle-meteo. You do not need any API key. Migrating to another cloud provider or your own server will remove the automatic location.

Using Node

npm install
# added 21 packages, and audited 22 packages in 2s

npm run dev
# ⎔ Starting local server...
# [wrangler:inf] Ready on http://127.0.0.1:8787

npm run deploy
# Total Upload: 179.64 KiB / gzip: 60.84 KiB
# Uploaded racle-meteo (25.80 sec)

Using Deno

Wrangler is not yet fully compatible with Deno and requires some npm. Need to come back here when Wrangler supports Deno. Uses npx for now.

deno install
# ...

deno task dev
# Task dev npx wrangler dev
# ⎔ Starting local server...
# [wrangler:inf] Ready on http://localhost:8787

deno task deploy
# Task deploy npx wrangler deploy
# Total Upload: 179.64 KiB / gzip: 60.84 KiB
# Uploaded racle-meteo (25.80 sec)

deno task test
# ok | 4 passed | 0 failed (3s)

Use
