I have written a javascript API which returns all the data from mongodb database on request. However it is sending the data s an array of objects and I want to get the simple json string. The statement returning the objects is
return db.collection('variants').find().toArray();
Do I need to append another function like JSON.stringify()? but I think that work for single object but not for array of objects as in my case.
var fetch = require('graphql-fetch');
const API_URL = `http://localhost:4000/graphql`
const query = `
{
variants{
VARIANT_ID
CHROM
}
}
`
fetch(API_URL)(query).then(data => console.log(data))
Okay I found the solution. All I need is JSON.stringify(data)
.
var fetch = require('graphql-fetch');
const API_URL = `http://localhost:4000/graphql`
const query = `
{
variants{
VARIANT_ID
CHROM
}
}
`
fetch(API_URL)(query).then(data => console.log(JSON.stringify(data)))
The following snippet will works properly.
fetch('/users.json')
.then(function(response) {
return response.json()
}).then(function(json) {
console.log('parsed json', json)
}).catch(function(ex) {
console.log('parsing failed', ex)
})
You can use mongoexport.
In order to perform this operation you need read access to the database.
Eg: mongoexport --db database [--collection traffic] --out file.json
