Deno 2.2 Improves Dependency Management and Expands Node.js Compatibility
Deno 2.2 enhances Node.js compatibility, improves dependency management, adds OpenTelemetry support, and expands linting and task automation for developers.
FlatDB it's a database based on JSON files, it's intended to help save and load informations from systems and processes that don't require hight data volume or read/write extreme performance.
You have a server that need to load the configurations but need to change it programatically some times, you won't install a whole database engine for such a simple thing...
To install FlatDB you just need to use npm npm install flatdb
Require the db an initialize it:
var flatdb = require('flatdb');
var db = new flatdb('./database'); //use any existing folder as db
//db will emit the event 'connect' when everything is ready to go
db.on('connect', function(){
doc = {
"hostname" : "localhost",
"port" : 8001,
"user" : "myuser",
"date" : new Date().getTime()
}
//insert some information in the database
db.save(doc, function(err){
if(err) throw err;
console.log('Finished insering information.');
//find some information on the database
db.find({"user" : "myuser"}, function(err, docs){
if(err) throw err;
console.log("We found: ", docs);
//now let's update every document that have the hostname
//"localhost" to use the port 1337
db.update({"hostname" : "localhost"}, {"port" : 1337}, function(err){
console.log('Finished updating...');
//let's delete every document that have the key "user"
//with the valye "myuser"
db.delete({"user" : "myuser"}, function(err){
if(err) throw err;
console.log('Finished deleting...');
});
});
});
});
});
For handling startup error, FlatDB emits a error
event, so you can catch it like:
var flatdb = require('flatdb');
var db = new flatdb('./nonexistent/path'); //force error
//db will emit the event 'connect' when everything is ready to go
db.on('connect', function(){
console.log('This message should not appear...')
});
//catch startup error here
db.on('error', function(err){
console.log('Oops:', err);
});
