I have a payload like this
{
"rows": [{
"id": "1234",
"data": {
"updatedby": "uid1",
"resource": {
"resourceid": "abcd"
}
}
}, {
"id": "1235",
"data": {
"updatedby": "uid2",
"resource": {
"resourceid": "pqrs"
}
}
}, {
"id": "1236",
"data": {
"updatedby": "uid3",
"resource": {
"resourceid": "bert"
}
}
}]
}
I need to extract the content of the RESOURCE tag only from the json payload. Can you please help me formulate the regex? The below is what I tried and it doesn't invoke the parser.data method.
var parser = JSONStream.parse(['rows', true, /^resource/]);
parser.on('data', function(data) {
console.log('received the payload -do something');
});
You don't need a Regex:
var JSONStream = require('JSONStream');
var fs = require('fs');
fs.createReadStream('data.json')
.pipe(JSONStream.parse('rows.*.data.resource'))
.on('data', console.log.bind(console))
which outputs:
{ resourceid: 'abcd' }
{ resourceid: 'pqrs' }
{ resourceid: 'bert' }
