How to encode cost models

export function encodeCostModels(costModels: Record<string, number>): Bytes {
  const sortedCostModelValues: number[] & { encodeCBOR?: any } = Object.entries(costModels)
    .sort(([key1], [key2]) => {
      if (key1 < key2) {
        return -1;
      } else if (key1 > key2) {
        return 1;
      } else {
        return 0;
      }
    })
    .map(([_, val]) => val);
  sortedCostModelValues.encodeCBOR = cbor.Encoder.encodeIndefinite;
  return Bytes.fromHex(cbor.encode(sortedCostModelValues).toString("hex"));
}

How to fix circular import

• Thanks to https://github.com/acrazing/dpdm - A robust static dependency analyzer for your JavaScript and TypeScript projects.

• Example:

  • I have tree like:

  ➜  ido git:(tony/ido-2.2) ✗ tree -L 1
  .
  ├── build-tx.ts
  ├── ido-v1.ts
  ├── ido.ts
  ├── index.ts
  ├── scripts
  ├── utils.ts
  ├── warehouse-v1.ts
  └── warehouse.ts

  • I try to run and got error:

  check_coin➜  monorepo git:(tony/ido-2.2) ✗ ./packages/backend/scripts/setup-ido.sh mainnet
  rebuild the script

  • Code:

    # ./src/ido/ido-v1.ts
    import invariant from "@minswap/tiny-invariant";
    import { IdoEvent, IdoOrder, Maybe, type NetworkEnvironment, Result, type Utxo } from "..";
    import { IdoWarehouseV1 } from "./warehouse-v1";
  
    export class IdoV1Event extends IdoEvent {
    }

  • Use dpdm to detect circular import:

  ➜  sdk git:(tony/ido-2.2) ✗ npx dpdm --no-warning --no-tree ./src/ido/ido-v1.ts | grep ido
  ✔ [130/130] Analyze done!
    58) src/index.ts -> src/ido/index.ts -> src/ido/build-tx.ts
    59) src/index.ts -> src/ido/index.ts -> src/ido/build-tx.ts -> src/ido/ido.ts
    60) src/index.ts -> src/ido/index.ts -> src/ido/build-tx.ts -> src/ido/ido.ts -> src/ido/warehouse.ts
    61) src/ido/ido-v1.ts -> src/index.ts -> src/ido/index.ts
    62) src/index.ts -> src/ido/index.ts -> src/ido/utils.ts
    63) src/index.ts -> src/ido/index.ts -> src/ido/warehouse-v1.ts

  • Observe: at 61): src/ido/ido-v1.ts -> src/index.ts -> src/ido/index.ts means: src/ido/ido-v1.ts -> src/index.ts -> src/ido/index.ts -> src/index.ts -> src/ido/ido-v1.ts
  • Solution: We need to update direct imports from src/ido/ido-v1.ts to src/ido/ido.ts
  • Updated code:

  import invariant from "@minswap/tiny-invariant";
  import { Maybe, type NetworkEnvironment, Result, type Utxo } from "..";
  import { IdoEvent, IdoOrder } from "./ido";
  import { IdoWarehouseV1 } from "./warehouse-v1";
  
  export class IdoV1Event extends IdoEvent {
  }

  • Re-run:

  ➜  monorepo git:(tony/ido-2.2) ✗ ./packages/backend/scripts/setup-ido.sh mainnet
  rebuild the script
  setup done
