code

1. enable valiation:

import { ValidationPipe } from "@nestjs/common";

app.useGlobalPipes(new ValidationPipe({
    transform: true,
}));

2. import ChainModule

import { ChainModule } from "@degoat/tx-builder-test";

@Module({
    imports: [
        ChainModule,
    ],
    controllers: [],
    providers: [],
})

3. sample for build swap transaction

import {
    BuildSwapParams,
    Chain,
    ChainProvider,
    DexProvider,
    Operation,
    SolanaProvider,
} from "@degoat/tx-builder-test";

@Controller()
export class AppController {
    constructor(
        private readonly chainProvider: ChainProvider,
    ) { }

    @Post("buildSwap")
    async buildSwap(@Body() body: BuildSwapParams) {
        const solanaProvider = this.chainProvider.provider<SolanaProvider>(Chain.Solana);
        const dexProvider = solanaProvider.provider<DexProvider>(Operation.Dex);

        const buffer = await dexProvider.buildSwap(body);
        return {
            tx: buffer.toString("base64"),
        };
    }
}
