level is not a function

[scenaristeur]

using level > 8.0.0

initialisation should be something like

import { Level } from 'level'
const bloidDb = new Level('./BloidDb')
levelgraph = require('levelgraph'),
jsonld     = require('levelgraph-jsonld'),
opts       = { base: 'http://scenaristeur.github.io/bloid' },
db         = jsonld(levelgraph(bloidDb), opts);
