Health Tracker

Simple tracking for water intake and sleep using JSON file.

Data Format

File: {baseDir}/health-data.json

{
  "water": [{"time": "ISO8601", "cups": 2}],
  "sleep": [{"time": "ISO8601", "action": "sleep|wake"}]
}

Add Water Record

When user says "uống X cốc" or "uống nước X cốc":

node -e "const fs=require('fs');const f='{baseDir}/health-data.json';let d={water:[],sleep:[]};try{d=JSON.parse(fs.readFileSync(f))}catch(e){}d.water.push({time:new Date().toISOString(),cups:CUPS});fs.writeFileSync(f,JSON.stringify(d));console.log('Da ghi: '+CUPS+' coc')"

Replace CUPS with number from user input.

Add Sleep Record

When user says "đi ngủ":

node -e "const fs=require('fs');const f='{baseDir}/health-data.json';let d={water:[],sleep:[]};try{d=JSON.parse(fs.readFileSync(f))}catch(e){}d.sleep.push({time:new Date().toISOString(),action:'sleep'});fs.writeFileSync(f,JSON.stringify(d));console.log('Da ghi: di ngu')"

Add Wake Record

When user says "thức dậy" or "dậy rồi":

node -e "const fs=require('fs');const f='{baseDir}/health-data.json';let d={water:[],sleep:[]};try{d=JSON.parse(fs.readFileSync(f))}catch(e){}const last=d.sleep.filter(s=>s.action==='sleep').pop();d.sleep.push({time:new Date().toISOString(),action:'wake'});fs.writeFileSync(f,JSON.stringify(d));if(last){const h=((new Date()-new Date(last.time))/3600000).toFixed(1);console.log('Da ngu: '+h+' gio')}else{console.log('Da ghi: thuc day')}"

View Stats

When user says "thống kê" or "xem thống kê":

node -e "const fs=require('fs');const f='{baseDir}/health-data.json';let d={water:[],sleep:[]};try{d=JSON.parse(fs.readFileSync(f))}catch(e){}console.log('Water:',d.water.length,'records');console.log('Sleep:',d.sleep.length,'records');const today=d.water.filter(w=>new Date(w.time).toDateString()===new Date().toDateString());console.log('Today:',today.reduce((s,w)=>s+w.cups,0),'cups')"

Update Record

To update last water entry:

node -e "const fs=require('fs');const f='{baseDir}/health-data.json';let d=JSON.parse(fs.readFileSync(f));d.water[d.water.length-1].cups=NEW_CUPS;fs.writeFileSync(f,JSON.stringify(d));console.log('Updated')"

Delete Record

To delete last water entry:

node -e "const fs=require('fs');const f='{baseDir}/health-data.json';let d=JSON.parse(fs.readFileSync(f));d.water.pop();fs.writeFileSync(f,JSON.stringify(d));console.log('Deleted')"
