diag

diag is the Algolia diagnostic tool.

Current diagnostics:

• full user-agent and timezone of the user
• current ip
• proxy detection
• geolocation and reverse geocoding using Nominatim
• navigation timing of the diag tool webpage
• /favicon.ico download timing from big websites
• Algolia /diag endpoint resource timing
• algoliasearch simple empty search
• Latency, bandwidth, ipv6 and mobile connection measurements using lognormal/boomerang

browser support

Targets modern evergreen browsers: Chrome ≥ 87, Edge ≥ 88, Firefox ≥ 78, Safari ≥ 14.1 (declared in browserslist and enforced via build.target in vite.config.js). Internet Explorer is not supported — the algoliasearch v5 client does not run there.

boomerang build

We use lognormal/boomerang as a way to gather even more information on the setup.

The frontend/static/boomerang file was built with:

git clone git@github.com:lognormal/boomerang.git
cd boomerang
npm install -g uglifyjs
make PLUGINS='plugins/rt.js plugins/bw.js plugins/ipv6.js plugins/mobile.js' MINIFIER='uglifyjs'
