cannot be imported correctly with TypeScript Node 16 module resolution mode

[Jack-Works]

TS requires JSBI.default.BigInt instead of JSBI.BigInt

[12wrigja]

Is this similar to js-temporal/temporal-polyfill#177 ?

Are the tsconfig settings mentioned on that issue the relevant ones here?

[Jack-Works]

maybe you need an export map and "type": "module" (maybe?) in package.json

[Dr-Nikson]

The issue is still there for 4.3.0

[12wrigja]

@Dr-Nikson can you please share your tsconfig settings and the exact error message you see?

Issues

facing the same issue in jessealama/decimal128

tsconfig.json jessealama/decimal128@b218eaa47#tsconfig.json

module: NodeNext
moduleResolution: NodeNext

package.json jessealama/decimal128@b218eaa47#package.json

type: module
dependencies.jsbi: ^4.3.0
devDependencies.typescript: ^5.1.3

Scenario 1: Using JSBI as the return type

Cannot use namespace 'JSBI' as a type`

Scenario 2: Creating a BigInt or use any methods

Property 'BigInt' does not exist on type 'typeof import("/../../node_modules/jsbi/jsbi")'

Possible resolution

Changing tsconfig to use "moduleResolution": "bundler" solve the issue

-"module": "NodeNext",
+"module": "ES2022",
-"moduleResolution": "NodeNext",
+"moduleResolution": "bundler",
