Läs mer om åtgärdsmappen actions-folder

Mappen actions för det här exempelprogrammet innehåller några JavaScript-filer och en mapp med namnet commerce. Den exempelfil som visas för JavaScript är ett utmärkt exempel som kan återanvändas om den är relevant för ditt arbete. Den här mappen kan spara tid när du ansluter till Adobe Commerce med OAuth och REST.

De faktiska namnen på mapparna i det här exemplet är godtyckliga, men om du vet deras namn kan du tolka exempelkoden. Genom att använda en meningsfull namnkonvention kan du undvika förvirring om programmet blir mer komplext.

Vem är den här videon till?

  • Utvecklare som är nybörjare i Adobe Commerce med begränsad erfarenhet av Adobe App Builder och som håller på att lära sig om åtgärdsmappen i exempelprogrammet.
