# Health Tracker Simple tracking for water intake and sleep using JSON file. ## Data Format File: `{baseDir}/health-data.json` ```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": ```bash 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": ```bash 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": ```bash 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": ```bash 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: ```bash 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: ```bash 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')" ``` ## Notes - Uses Node.js built-in modules only - File auto-created if missing - All timestamps in ISO8601 format
