As of Node.js 10.0.0, 100% of ES2018 is supported. If you know that you are targeting that version or newer, the optimal config would look like this: “module”: “commonjs” Node.js is on its way to add ES-Modules, but for now we’ll have to stick with CommonJS. “target”: “es2018” This tells TypeScript that it’s okay to … Read more
Keys in leveldb are arbitrary binary sequences. Clients implement comparators to define ordering between keys. The default comparator for leveldb is something equivalent to strncmp. Chrome’s comparator for Indexed DB’s store is more complicated. If you try and use a leveldb instance with a different comparator than it was created with you’ll observe keys in … Read more
Since Typescript 2.9 it is possible to compile your library with the declarationMap flag ./node_modules/typescript/bin/tsc -p . –declarationMap Doing so creates a declaration map file (dist/ActionApi.d.ts.map) and a link to the map at the bottom of the corresponding d.ts file //# sourceMappingURL=ActionApi.d.ts.map When VSCodes encounters such a declarationMap it knows where to go to and … Read more
Another way is to use text argument with prefix – which will exclude this or that field from the result: Entity.find({ … }, ‘-_id field1 field2’, function(err, entity) { console.log(entity); // { field1: ‘…’, field2: ‘…’ } });
For future people: Here is 2 very simple Node.js apps that use socket.io to connect, send and receive messages between each other. Required package is: npm install socket.io Node-App-1 server.js: var io = require(‘socket.io’).listen(3000); io.on(‘connection’, function (socket) { console.log(‘connected:’, socket.client.id); socket.on(‘serverEvent’, function (data) { console.log(‘new message from client:’, data); }); setInterval(function () { socket.emit(‘clientEvent’, Math.random()); … Read more
I have a workaround for the adding proper extension of files. If you use path node module var multer = require(‘multer’); var path = require(‘path’) var storage = multer.diskStorage({ destination: function (req, file, cb) { cb(null, ‘uploads/’) }, filename: function (req, file, cb) { cb(null, Date.now() + path.extname(file.originalname)) //Appending extension } }) var upload = … Read more
app.get(‘/fruit/:fruitName/:fruitColor’, function(req, res) { var data = { “fruit”: { “apple”: req.params.fruitName, “color”: req.params.fruitColor } }; send.json(data); }); If that doesn’t work, try using console.log(req.params) to see what it is giving you.
