jukebox

Web-Based jukebox for a local Music Directory

Tech-Stack

• typescript / node / prisma
• handlebars templating engine on the backend
• custom-written saslauthd authentication
• bootstrap in combo with purgecss (works nicely!!)
• handling of browser sessions (custom!)

musings on session and cookie in the middleware

"A Session is always device (and even browser) specific"

session.gotLogin: boolean
session.gotLogout: boolean
session.needsSave: boolean

BEFORE

sessId (cookie)	memcache	what to do
✅	✅	normal Session
✅	❌	cannot find memcache, Server dictates new sessId
❌	✅	new sessId, new cookie (memcache auto evict, will never find again)
❌	❌	new sessId, new cookie

AFTER LOGIN (during next())

session.username is beeing set, meaning:

• send cookie (/login onto a working session is not quite realistic, but resending a known cookie again is ok)
• save to memcached

AFTER LGOUT (during next())

• destroy cookie
• remove from memcached, if it came from it.

AFTER MODS (during next())

• save to memcache

AFTER nothing

• do nothing

Notes on syncing

• Path insertion is fast (by processListingFile())
• after this, most files are still correct

Verify all Tracks - need to stat() all: YES

• DB View: some files do not exist on filesystem anymore (thru picard)
• DB View: some files on filesystem are newer (tags & sha256 needs regeneration)

setting inode to NULL

I now get files with

• verifiedAt NULL or a date

verifiedAt .. timestamp of last full verification

inode, sizeBytes .. comes thru stat

ext, mimeType .. comes thru bufferMimeType
