1. Aynan 1-chi nuqta sababli, soatlab vaqtimni sarflab hech qanday pul ololmagan vaqtlarim ham bo'lagan, misol uchun bir oy sarflab qilgan freelancing ishim uchun 1500$ pul olomaganman.

2. Ayan shu 2-chi nuqta orqali ham freelancing orqali eng ko'p pul ishlab topganman. Chunki freelancer bo'lishda anchagina raqobat kuchli, aynan shu yerda soft skill yordam beradi. Misol uchun, 2-tadan oshiq tilda gaplasha olishim anchagina yordam bergan.

Use Snyk.

Xarbir dastur ortida security bo'yicha maxsus ishlar olib boriladi, bazi kampaniyalarda maxsus dasturchilar bo'lsa, ba'zilarida bu automatic service yordamida bajariladi. Bugungi yozmoqchi bo'lganim ham automatic service bo'yicha bo'ladi yani Snyk. Snyk 2015 yilda asos solingan bo'lib, hozirda esa 1.400 dan oshiq employee ga ega bo'lgan security driven company xisoblanadi. Snyk dasturga integratsiya qilinganda son'g CLI, IDE va projectni CI/CD pipeline larda run qilish mumkin. Bizda esa bu CI/CD pipeline mizda mavjud, xarsafar githubga code push qilinganda Snyk automatic codeni scan qilida, agar qandaydur vulnerability topilsa darxol CI/CD fail bo'ladi, commit owner va project owner larga vulnerability haqida email jo'natadi. Messageda vulnerability qayerda kelganligi, nima sababdan bo'lganligi va eng muhumi qanday tog'irlash mumkinligi haqida documentation ham bo'ladi. Snyk xatto biz ishlatayotgan packageni ichidagi inner packagelarni ham scan qiladi, yani Pavel Durov aytgandek "Back Door" muammosini osonlik bilan hal qilish mumkin, bu esa bizga ko'proq coffee ichishimiz uchun vaqt beradi :)

Shuning uchun ham deyarli hamma projectlarda Snyk scan pipelanide mavjuda va millionlab dasturchilar tomonidan ishlatib kelinadi. Ayniqsa Amazon (AWS), Google va Atlassion ham ishlatib keladi. Shunga bo'lsa kerak men/biz Snyk ishlatamiz.

Use Sentry.

Deyarli hamma kampaniyada ishlatib kelinadigon monitoring uchun service, yani kodimizni xar qanday environmentda monitor/track qilishimizga yordam beradi. Ushbu service juda qulay bo'lib, dasturga kirgan xar bir userni vebsaytda bajarayotgan ishini record qilib boradi, ayan shu xusisiyat uchun ham 4 milliondan oshiq dasturchilar tomonidan ishlatib kelinadi. Lekin bu recorded video maxsus algoritm tomonidan avtomatik o'chirib boriladi, yani user qilgan barcha ish emas balki user bajarayotganda feature uchun xatolik chiqsa 5 second forward/backward* (5 sekund oldi/orqa) vaqtlarni qoldirgan xolatda bizga avtomatik email jo'natadi. Bu orqali dasturdagi xar qanday xatolikni real vaqt asosida topish va tuzatish mumkin bo'ladi. Sentry ni bundan boshqa featurelari juda ko'p, bekorga ham Github, Disney, Atlassian, Cisco kampaniyalar tomonidan ishlatib kelinmaydi. Hozirgi vaqtda esa React teamni o'zi katta etibor qaratgan, shuning uchun ham bu yil bo'lib o'tgan React Conf da Sentry team tomonidan showcasing bo'lib o'tgan, quyidagi link orqali showcasingni ko'rishingiz mumkin.

Knip the Code.

Ish jarayonida workplace juda mess (tartibsiz) bo'lib ketadi, ayniqsa bir feature ustida ko'p dasturchilar ish olib borsa. Qaysidur manoda eslint, prettier, biome va shunga o'xshash kodni lint qilib beruvchi, yoki standard asosiyda kod yozishga majburlash orqali kodni yaxshi xolatga keltirish mumkin. Lekin katta codebaseda faqatgina quyidagi linterlar unchalik foyda bermaydi, ayniqsa 10lab dasturchilar bitta feature ustida ish olib borsa. Chunki kodni faqat format qilish orqali boshqarish qiyin, xardoimgi holatda ishlatilmayotgan codes, dependencies, dev dependencies, duplicates va files larni kuzatib turish anchagina bosh og'riq bo'ladi, muammoni yechimi ham shu "bosh og'riq"da. Chunki bunday muammolarni tog'irlash soatlab reviweing ni talab qiladi, bazida esa kunlab. Bunday muammolarning oson yechima shunchaki kodni knip qilish, qaytaraman knip qilish orqali hal qilishimiz mumkin "qaysidur manoda".


Knip JS/TS kodlarni avtomatik tarzda declutter qilib beradi, yani xar bir fileni avtomatik tarzda run qilish va analayz qilish orqali ishlatilmayotgan codes, dependencies, dev dependencies, duplicates va files aniqlab olishimiz mumkin. Bu esa soatlab vaqtimizni tejaydi. Shunga ham, weekly code reviewda knip ishlataman/ishlatamiz.
