const grib2Data = require('eccodes-data-grib2')
const ecLib = new EcLib()
const demo = async () => {
/*
* (optional)
* This will create a temporary directory in os.tmpdir()
* containing the required definitions files
*/
await ecLib.load([
grib1Data,
grib2Data
])
/*
* It is then possible to retrieve the adequate
* environment variables for using the library:
* {
* LD_LIBRARY_PATH: '[..]/eccodes-lib/lib',
* ECCODES_DEFINITION_PATH: '/tmp/eccodes-lib-[..]',
* ECCODES_SAMPLES_PATH: '[..]/eccodes-lib/share/samples'

* Or then the temporary folder will automatically
* be deleted on process exit or crash.
