Datason

A database consisting of json files on disk.

Every table is a directory and every object is a json file... the way it should be.

Docs

Saving an object is easy.

const db = require("datason");
 
db.connect("<path to db dir>").then((db) => {
  db.createTable("table");
  db.table.register("id", { data: "hello world" });
});

The object will then be created and accessible via dot notation, i.e. db.table.id.data.data === "hello world"

Updating a registered object is super easy!

table.register("id", { data: "hello world" });
table.id.data.data = "hello universe";
table.id.data.data.save.then((_) => console.log("save complete"));

Loading should never be explicitly required so when calling connect it will load the database into memory.

Index

A table can be time indexed if desired like so:

db.createTable("time", { index: Index.TIME });

It will then keep an index of when all the entries are added. The index consists of buckets containing the IDs. By default the bucket size is 50 and it is used as a rough filtering for when the index is queried.

The time index can be queried like this to get everything inserted the past second:

db.get("time").getFrom(new Date().getTime() - 1000);
