import { NearBindgen, near, call, view } from 'near-sdk-js';
@NearBindgen({})
class HelloNear {
greeting: string = 'Hello';
@view({}) // This method is read-only and can be called for free
get_greeting(): string {
return this.greeting;
}
@call({}) // This method changes the state, for which it cost gas
set_greeting({ greeting }: { greeting: string }): void {
near.log(`Saving greeting ${greeting}`);
this.greeting = greeting;
