Inserts new object to your json file without overwriting the content.
why use this?
json-updater doesn't rewrite the whole file but appends the new object to your json file object, which makes it much faster.
npm install --save json-updater
insert(filename, obj[,space], callback)
obj object(s) to insert
The optional space argument formats your obj. Default 0 spaces.
Using default space:
var jsonUpdater = require('json-updater');
var file = __dirname + '/users.json';
var obj = {
"1": {
"first_name": "Will",
"last_name": "Smith"
}
};
//you can also insert multiple objects
var multiObj = {
"2": {
"first_name": "Google",
"last_name": "Chrome"
},
"3": {
"first_name": "Mozilla",
"last_name": "Firefox"
},
"arr": [
"foo",
"bar"
]
}
jsonUpdater.insert(file, obj, function (err) {
if(err) return console.error(err);
//-- your code
});With space or tab:
jsonUpdater.insert(file, obj, 1, function (err){
if(err) return console.error(err);
//-- your code here...
});
jsonUpdater.insert(file, obj, '\t', function (err) {
if(err) return console.error(err);
//-- your code here...
});read(filename[,space], callback)
The callback gets two arguments (err, data) where data is the content of the file
The optional space argument formats the data from callback.
jsonUpdater.read(file, '\t', function (err, data) {
if(err) return console.log(err);
console.log(data);
});
