Cannot find name 'bigint', 'BigInt64Array, 'BigUint64Array

[rtyx]

Hi! I'm trying to implement this in an Angular 7 project using "typescript": "3.1.1", but I get the following error messages. Any idea how could I solve it? Thanks.

ERROR in node_modules/stacktrace-parser/node_modules/type-fest/source/basic.d.ts(14,4): error TS2304: Cannot find name 'bigint'.
node_modules/stacktrace-parser/node_modules/type-fest/source/basic.d.ts(35,4): error TS2304: Cannot find name 'BigInt64Array'.
node_modules/stacktrace-parser/node_modules/type-fest/source/basic.d.ts(36,4): error TS2304: Cannot find name 'BigUint64Array'.

Spontanously: no clue. Never seen that kind of error before.

But that sounds like a problem within the type-fest dependency. Have you tried updating it, or a different typescript versoin?

They say that BigInt is available in TypeScript 3.2, but even then, there are settings you need to change to make it work. See this issue for more info https://stackoverflow.com/questions/59456390/using-bigint-in-typescript
