babel-plugin-transform-jsbi-to-bigint
Compile JSBI code that works in today’s environments to native BigInt code.
Example
Input using JSBI:
import JSBI from 'jsbi';
const a = JSBI.BigInt(Number.MAX_SAFE_INTEGER);
const b = JSBI.BigInt('42');
JSBI.add(a, b);
JSBI.subtract(a, b);
JSBI.multiply(a, b);
JSBI.divide(a, b);
JSBI.remainder(a, b);
JSBI.exponentiate(a, b);
JSBI.leftShift(a, b);
JSBI.signedRightShift(a, b);
JSBI.bitwiseAnd(a, b);
JSBI.bitwiseOr(a, b);
JSBI.bitwiseXor(a, b);
JSBI.unaryMinus(a);
JSBI.bitwiseNot(a);
JSBI.equal(a, b);
JSBI.notEqual(a, b);
JSBI.lessThan(a, b);
JSBI.lessThanOrEqual(a, b);
JSBI.greaterThan(a, b);
JSBI.greaterThanOrEqual(a, b);
JSBI.EQ(a, b);
JSBI.NE(a, b);
JSBI.LT(a, b);
JSBI.LE(a, b);
JSBI.GT(a, b);
JSBI.GE(a, b);
a.toString();
JSBI.toNumber(a);
a instanceof JSBI;
JSBI.asIntN(64, JSBI.BigInt('42'));
JSBI.asUintN(64, JSBI.BigInt('42'));
Transpiled output using native BigInt
s:
const a = BigInt(Number.MAX_SAFE_INTEGER);
const b = 42n;
a + b;
a - b;
a * b;
a / b;
a % b;
a ** b;
a << b;
a >> b;
a & b;
a | b;
a ^ b;
-a;
~a;
a === b;
a !== b;
a < b;
a <= b;
a > b;
a >= b;
a == b;
a != b;
a < b;
a <= b;
a > b;
a >= b;
a.toString();
Number(a);
typeof a === 'bigint';
BigInt.asIntN(64, 42n);
BigInt.asUintN(64, 42n);
See the JSBI documentation for more information.

How to publish a new release
-
On the
main
branch, bump the version number inpackage.json
:npm version patch -m 'Release v%s'
Instead of
patch
, useminor
ormajor
as needed.Note that this produces a Git commit + tag.
-
Push the release commit and tag:
git push
Our CI then automatically publishes the new release to npm.
