Feasbl JavaScript SDK

@feasbl/sdk provides JavaScript builders for Feasbl optimization inputs:

• .jia models for CP and LP workflows
• PDDL domain/problem files for planning workflows
• a small direct-submit client for the Feasbl API

Install

npm install git+ssh://[email protected]/Feasbl/feasbl-js.git

Use

import * as feasbl from "@feasbl/sdk";

const lp = feasbl.lp("production");

const chairs = lp.real("chairs", { min: 0 });
const tables = lp.real("tables", { min: 0 });

lp.maximize(lp.add(lp.mul(45, chairs), lp.mul(80, tables)));
lp.constraint("wood", lp.le(lp.add(lp.mul(2, chairs), lp.mul(4, tables)), 120));

console.log(lp.toJia());

See examples/ for CP, LP, and planning examples.

Test

npm test

Coverage

Coverage uses Node's built-in test runner with c8 instrumentation.

npm run coverage

Smoketest

Submit a small model to the live API:

npm run smoketest -- <fsbl_api_key>

The target can be overridden with FEASBL_API_BASE_URL, FEASBL_COMPUTE_TIER_ID, or FEASBL_TIME_LIMIT_S.
