tiddlywiki5 - Why heroku app doesn't save new file with Tiddlywiki? -
have met issue me before? have deployed tiddlywiki5 heroku app @ https://jameswiki.herokuapp.com . displayed , worked expected @ runtime. however, after server (web dyno) sleeping , wakeup (often after 1 hour inactive), clear. have checked console in heroku when creating new tiddle, still said new tiddle has been saved, in fact, no new tiddle saved tiddlers folder. below script install , run it: in package.json { ... "scripts": { "start": "tiddlywiki . --server", "postinstall": "npm install -g tiddlywiki" } } in procfile web: tiddlywiki . --server $port $:/core/save/all text/plain text/html "" "" 0.0.0.0 help me fix issue. thanks. heroku's filesystem ephemeral - exists while dyno exists. when dyno restarts or ends (as when app goes sleep), new 1 have fresh, empty filesystem. if want files persist, need save them off database or amazon s3 long-term
