Viewsmodule.export in typescript. import json list
It seems simple, this operates in javascript, but I'm a bit confused about typescript's closest equivalent. I'm trying to use module.exports in the way I know from javascript, passing data the json list data between 3 files.
in javascript the main file basically works as this: - main.js :
const { mainnet: addresses } = require("./addresses");
const token0 = addresses.tokens.busd;
so, main.ts would be? (i believe main issue is here):
import { mainnet } from "./addresses/index";
token0 = mainnet.tokens.busd;
then typescript index.ts in ./address/index.ts (i believe this functions properly):
import tokensMainnet from './tokens-mainnet.json';
declare var module: any;
// "allowSyntheticDefaultImports" = true
module.exports = {
mainnet: {
tokens: tokensMainnet
}
};
and tokensmainnet.json
{
"busd": "0xe9e7CEA3DedcA5984780Bafc599bD69ADd087D56",
"wbnb": "0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c"
}
i can see from the metadata it's functioning:
so I believe the main problem with with importing this module in the main.ts
I've grazed over some sources such as with no luck https://www.typescriptlang.org/docs/handbook/modules.html

in typescript
add
"resolveJsonModule":true
to package.json:
" Allows importing modules with a ‘.json’ extension, which is a common practice in node projects. This includes generating a type for the import based on the static JSON shape." -https://www.typescriptlang.org/tsconfig#resolveJsonModule
so add to main.ts:
import * as data from "./addresses/tokens-mainnet.json"
//...program code...
constructor(){
let tokenAddress = data
console.log(tokenAddress.busd)
}
:)
