Database configuration

For now, two types of storage are supported: Redis and local filesystem.

A Redis URL can be passed through an environment variable, instead of having it stored in the configuration file:

DB__REDIS_URL=redis://rediscloud:[email protected]:13714

Run your application like this:

DB__REDIS_URL=redis://url moniteur [options]

Note that REDIS_URL and REDISCLOUD_URL are also valid environment variables.

npm run dev

Roadmap

• Make moniteur a working node module
• Run as some sort of daemon that monitors asset metrics every X seconds
• Monitor JavaScript files
• Unit / Integration tests
• Option to filter graphs by time range (last 7 days, last 30 days, last year)
• Slack Bot

Ideas

• Providing a page's URL, scrape all assets out of it and analyse them
• Parse all assets in a particular directory
• Asset size budget limits
• Email alert when budget is almost reached or exceeded
• Weekly email recaps
