subgraph - 定义对象类型时出错'

Question

I'm developing subgraph for indexing blockchain events, but I get error when defining and object

⠋ Compile subgraphERROR TS2322: Type '<object>' is not assignable to type 'i32'.

 export const FARMS_CONTRACT_NAMES = {
  BALANCER_LIQUIDITY: 'balancerLiquidity',
  GIV_LIQUIDITY: 'givLiquidity',
  GIV_ETH: 'givETH',
  GIV_HNY: 'givHny'
};

如果你想为你的配置使用一个对象，你需要为它定义一个类，因为 AS 没有隐式对象：

class Config {
  BALANCER_LIQUIDITY: string;
  GIV_LIQUIDITY: string;
  GIV_ETH: string;
  GIV_HNY: string;
}

export const FARMS_CONTRACT_NAMES: Config = {
  BALANCER_LIQUIDITY: 'balancerLiquidity',
  GIV_LIQUIDITY: 'givLiquidity',
  GIV_ETH: 'givETH',
  GIV_HNY: 'givHny'
};

但是单独导出值也有好处：

更少的源代码
您只能导入部分配置
没有类开销

经过一些试验和错误以这种方式改变它解决了我的问题：

export const BALANCER_LIQUIDITY = 'balancerLM';
export const GIV_LIQUIDITY = 'givLM';
export const GARDEN_POOL = 'gardenPool';
export const GIV_ETH = 'givETH';
export const GIV_HNY = 'givHNYPool';

我认为汇编脚本在定义对象时存在问题（在函数输入参数中你不能使用 object {}）
