no-bigint-literals

Purpose and behavior

Use BigInt construction instead of bigint literal syntax.

Official Effect rule, vendored at b1d200c40a1dad69def51ebdbf0a1a612a12b8ac. Reports literal nodes whose runtime value is bigint and replaces them with BigInt(""). Numeric separators and alternate bases are normalized by the literal value. This does not prohibit BigInt constructor calls.

Options

No configurable options. Enable with "rules/no-bigint-literals": "error".

Invalid example

const value = 123n

Valid example

const value = BigInt("123")

Fixes and exceptions

This rule supplies an automatic code fix. Review the resulting import bindings and runtime resolution before applying it.

For a genuine boundary exception, use an oxlint-disable-next-line rules/no-bigint-literals -- reason comment. Examples illustrate this rule alone and may omit imports and declarations.
