I am attempting to do some error handling for a csv file. When changing the name of the file to something that does not exists,
Error: ENOENT: no such file or directory, open 'testdat.csv'
is displayed but the on error event is not fired.
Here is the current implementation:
const csv = require('csv-parser');
const fs = require('fs');
fs.createReadStream('testdat.csv')
.pipe(csv())
.on('open', () => {
})
.on('headers', (headers) => {
validateHeader(headers);
})
.on('data', (data) => {
temp.push(data);
})
.on('end', () => {
validateData(temp);
})
.on('error', (err) => {
console.log(err);
});
You need to attach the error event handler before piping.
const csv = require('csv-parser');
const fs = require('fs');
var readable = fs.createReadStream('testdat.csv');
readable.on('error', (err) => {
console.log(err);
});
// pipe function returns different stream
var writable = readable.pipe(csv())
writable.on('error', (err) => {
console.log(err);
});
