Loki.js is a filesystem based database (like Sqllite), but that serializes to Javascript.<\/p>\n
To create an empty database in Node, you can do the following – this creates an empty database.<\/p>\n
\nconst loki = require(\"lokijs\");\nconst db = new loki(\"db.json\");\ndb.save();\n<\/pre>\nOnce you have a database, you can import existing files into it. If you want to do this without erasing the database each time, you have to check if the data collection exists each time.<\/p>\n
\nconst fs = require(\"fs\");\nconst files = fs.readdirSync(\"1\/\");\n\nconst talks = db.addCollection(\"talks\");\nfunction loadCollection(colName, callback) {\n db.loadDatabase({}, () => {\n let existingCollection = db.getCollection(colName);\n\n if (!existingCollection) {\n existingCollection = db.addCollection(\"talks\");\n }\n\n callback(existingCollection);\n });\n}\n\nloadCollection(\"talks\", (talks) => {\n const allFiles = fs.readdirSync(\".\/1\");\n\n for (let i in allFiles) {\n let filename = \"1\/\" + files[i];\n const talk = JSON.parse(fs.readFileSync(filename));\n talks.insert(talk);\n } \n \n db.saveDatabase();\n});\n<\/pre>\nOnce you do this, you’ll have a massive JSON file to work with further.<\/p>\n","protected":false},"excerpt":{"rendered":"
