Unexpected compile / type error when using Promise.all #35136
Description
TypeScript Version: 3.7.2
Search Terms:
- Promise.all typing
Code
index.ts
type RandomType = {};
const getRandomValue = async (): Promise<RandomType> => {
return {};
};
const getResults = async (): Promise<{ data: string[] }> => {
return { data: ['a', 'b', 'c'] };
};
const run = async () => {
const [random, { data }] = await Promise.all([getRandomValue(), getResults()]);
console.log(random, data);
};
run();tsconfig.json
{
"compilerOptions": {
"target": "esnext",
"lib": ["esnext", "dom"]
},
"exclude": ["node_modules"],
"include": ["./**/*.ts"]
}
Expected behavior:
Compiles successfully.
Actual behavior:
Compile error: "Property 'data' does not exist on type 'RandomType'."
Seems to still compile the js file even though it shows a compile error.
Does not run with ts-node though.
