    npm version

    vgrib2

    A library for parsing GRIB files written entirely in Typescript

    Installation

    $ npm install vgrib2
    

    Usage

    Parse GRIB File

    import fs from 'fs'
    import { GRIB } from 'vgrib2'
    
    const gribFile = fs.readFileSync('./path/to/file.grib2')
    
    const grib = GRIB.parse(gribFile)
    // No Table Lookup (useful for adding new tables)
    const gribNoLookup = GRIB.parseNoLookup(gribFile)
