Native Node.js bindings for the HiGHS optimization solver.
import * as highs from 'highs-solver';
// Solves an LP model, outputting regular progress updates (gap, ...).
const solution = await highs.solve('model.lp', {
monitor: highs.solveMonitor().on('progress', console.log),
options: {time_limit: 600, mip_rel_gap: 0.05},
style: highs.SolutionStyle.PRETTY,
});
Packages
The following packages are available:
highs-solver
, high-level idiomatic TypeScript APIhighs-addon
, low-level API mirroring the underlying C++ solver's

- https://github.com/lovasoa/highs-js, WebAssembly solver port. Both projects
are complementary:
highs-js
runs in browsers and is well-suited for Web Workers;highs-solver
provides non-blocking native performance on Node.js (~3x faster). - https://github.com/ERGO-Code/HiGHS, the underlying C++ HiGHS optimization
solver which both this repository and
highs-js
bind to.
