- Add @typescript-eslint/parser and @typescript-eslint/eslint-plugin as
direct devDependencies (were only transitive, not linked in node_modules)
- Add files pattern and parserOptions.project to eslint.config.mjs so
ESLint finds and type-checks src/**/*.ts files correctly
- Run prettier --write to fix formatting across all src files
Computes the midpoint of the night (Maghrib to Fajr), commonly used as
the Isha prayer endpoint. Also works with sunrise as the second anchor
for the astronomical variant.
Closes#1
- Extract magic numbers into named constants (DHUHR_OFFSET_MINUTES,
ANGLE_MIN/MAX, LAT_SCALE) with source citations for MCW coefficients
- Add input validation (RangeError) for lat, lng, tz, elevation on all
public API functions (getTimes, getTimesAll)
- Optimize solar ephemeris: computeAngles() returns declination so
getTimes/getTimesAll reuse it for Asr instead of computing twice
- DRY: shared constants.ts for DEG, Dhuhr offset, angle bounds
- Improve MethodEntry type with labeled tuple elements and NaN docs
- Add stricter tsconfig (noImplicitReturns, noFallthroughCasesInSwitch)
- Switch tests to node:test framework (TAP output, describe/it blocks)
- Add 8 new input validation tests (104 ESM + 13 CJS total)
- Add ESLint + Prettier with CI lint job
- Remove src/ from npm package files (smaller published tarball)
- Document NaN return behavior in JSDoc for getTimes/getTimesAll
