Is there any library available in node.js/javascript that allows an individual to use mongoimport
in code?
To my understanding, mongoimport is kinda like an .exe, which you have to execute it first before being able to use its text input environment.
Is it possible to execute mongoimport in my code and then parse whatever commands I need directly in my code?
My current algorithm involves:
fs.appendFile('log.txt',JSON.stringify(obj, null, 2));
obj is an object which specifies what functions to parse into JSON.stringify
with the res
method of node.js (which requests HTTP responses)
var obj = {};
obj.url = hostNames[i];
obj.statusCode = res.statusCode;
obj.headers = res.headers;
Then I use mongoimport to import this JSON doc into my MongoDB.
mongoimport --host localhost -db scrapeapp -collection scrape --file log.txt --jsonArray
This method is obviously inefficient. I would like to do all these steps in one going.
Help appreciated
This is how I do it in my code
let exec = require('child_process').exec
let command = 'mongoimport -d database -c collection --file import.json'
exec(command, (err, stdout, stderr) => {
// check for errors or if it was succesfuly
cb()
})
I exec the mongoimport command and then I do pass the cb next the code to be accesible, or if you do not use an asynchronous style you can do it synchronously with child_process.execSync(command[,options])
