Gatsby clean

A gatsby clean parancs a Gatsby projektben a cache és a generált fájlok törlésére szolgál. Konkrétan a következőket teszi:

1. Törli a cache-t

A Gatsby által generált .cache könyvtár tartalmát törli.
Ez a könyvtár a build folyamat során létrehozott átmeneti adatokat tartalmazza (pl. GraphQL lekérdezések eredményei, képgenerálási adatok).
Ha ez a cache megsérül vagy elavult, előfordulhatnak hibák vagy nem kívánt viselkedések. A gatsby clean segít ezeket megoldani.

2. Törli a public mappát

Az összesített build fájlokat tartalmazó public könyvtárat is törli.
Ez a mappa a kész weboldal statikus fájljait (HTML, CSS, JS, képek) tartalmazza, amelyeket a build folyamat során hoz létre a Gatsby.

3. Új build alapok

A következő build teljesen tiszta környezetben történik, újraépítve minden fájlt és adatot.
Ez különösen akkor hasznos, ha váratlan viselkedést tapasztalsz, például helytelenül renderelt komponenseket vagy elavult adatokat.

Mikor érdemes futtatni?

Cache probléma gyanúja esetén: Ha olyan hibát tapasztalsz, amely látszólag nem a kód változásai miatt következik be.
Új függőségek vagy pluginok hozzáadása után: Ha új függőséget vagy Gatsby plugint adsz a projektedhez, és az nem működik megfelelően.
Deploy hibák elkerülése érdekében: Ha biztos akarsz lenni abban, hogy a build folyamat teljesen tiszta.

Hogyan használod?

Egyszerűen futtasd a következő parancsot a terminálban a projekt gyökérkönyvtárában:

gatsby clean

Utána

A gatsby clean után általában új buildet kell indítani:

gatsby develop

vagy

gatsby build

Ez biztosítja, hogy a törölt fájlokat és cache-t újra generálja a Gatsby.
