示例1: levelup

import encoding from 'encoding-down'
import level from 'level-js'
export default levelup(encoding(level('worker'), {valueEncoding: 'json'}))
示例2: Error
constructor(params) {
const { path, createIfMissing, errorIfExists } = params;
let basePath;
if (!path) {
basePath = `${os.homedir()}/.bitcore`;
try {
fs.mkdirSync(basePath);
} catch (e) {
if (e.errno !== -17) {

db.get(LEVELDB_KEY, (err, value) => {
if (err) { res.json(null); }
res.json(value);
db.close(); // どのタイミングでcloseすればいいのかイマイチわからない。
});
// db.close();
});示例4: init
init() {
this.inst = levelup( leveldown( path.resolve( this.dir, "commands" ) ) );
}示例5: createDb
