I need to download a file on the server using ssh from remote to local.
I'm using the simple-ssh module from npm link to npm module

I can update a file that is already on the server, however I need to download such a file

var SSH = require('simple-ssh');
let ssh = new SSH(
 host: 'remote_server_ip',
 user: 'my_user',
 pass: 'my_pass'
 );
 
 ssh.exec(`cat > $filePath`, 
 in: fs.readFileSync('/home/raphael/Documentos/teste.bin')
 ).start();
 
 //my filePath /arq_soa/arquivos_validador/Envio/tst_acesso

Can someone help me?, i'm lost

After help of @Carlos Jafet Neto, my code has changed, now:

var Client = require('ssh2-sftp-client');
let sftp = new Client
 sftp.connect(
 host: 'remote_server_iṕ',
 port: 22,
 username: 'username',
 password: 'password'
 ).then(() => 
 return sftp.list(`$pathArquivoValidador`);
 ).then(async (data) => 
 let len = data.length;
 await data.forEach(x => 
 let remoteFilePath = `$pathArquivoValidador` + params.nmArquivo; 
 sftp.get(remoteFilePath).then((stream) => 
 let file = './home/raphael/Documentos/' + params.nmArquivo;
 fs.writeFile(file, stream, (err) => 
 if (err) console.log(err);
 );
 );
 // console.log(x);
 );
 ).catch((err) => 
 console.log(err, 'catch error');
 );

but the sftp.get are bringing me the following error

[Error: ENOENT: no such file or directory, open './home/raphael/Documentos/tst_acesso']
errno: -2,

Try to get first only the files that are in your folders without using variables, using your path as a string to eliminate errors.

var Client = require('ssh2-sftp-client');
let sftp = new Client
 sftp.connect(
 host: 'remote_server_iṕ',
 port: 22,
 username: 'username',
 password: 'password'
 ).then(() => 
 return sftp.list('/');
 ).then(async (files) => 
 console.log(files);
 len = files.length;
 await files.forEach(x => 
 let remoteFilePath = '/' + x.name;
 sftp.get(remoteFilePath).then((stream) => 
 let file = './ftp/' + x.name;
 fs.writeFile(file, stream, (err) => 
 if (err) console.log(err);
 );
 );
 );
 ).catch((err) => 
 console.log(err, 'catch error');
 );

To get a single file:

var Client = require('ssh2-sftp-client');
let sftp = new Client
 sftp.connect(
 host: 'remote_server_iṕ',
 port: 22,
 username: 'username',
 password: 'password'
 ).then(() => 
 let remoteFilePath = '/' + fileName;
 sftp.get(remoteFilePath).then((stream) => 
 let file = './ftp/' + x.name;
 fs.writeFile(file, stream, (err) => 
 if (err) console.log(err);
 );
 sftp.end();
 );
 ).catch((err) => 
 console.log(err, 'catch error');
 );

Use this to close the ftp connection:

sftp.end();

  You would need to make a get request to the browser with the full path of your file! You can do this with the request module. Take a look: npmjs.com/package/request

  Yes. If you now already the file you do not even need the loop. I will update with this extra solution.

  You would need to make a get request to the browser with the full path of your file! You can do this with the request module. Take a look: npmjs.com/package/request

Try to get first only the files that are in your folders without using variables, using your path as a string to eliminate errors.

var Client = require('ssh2-sftp-client');
let sftp = new Client
 sftp.connect(
 host: 'remote_server_iṕ',
 port: 22,
 username: 'username',
 password: 'password'
 ).then(() => 
 return sftp.list('/');
 ).then(async (files) => 
 console.log(files);
 len = files.length;
 await files.forEach(x => 
 let remoteFilePath = '/' + x.name;
 sftp.get(remoteFilePath).then((stream) => 
 let file = './ftp/' + x.name;
 fs.writeFile(file, stream, (err) => 
 if (err) console.log(err);
 );
 );
 );
 ).catch((err) => 
 console.log(err, 'catch error');
 );

To get a single file:

var Client = require('ssh2-sftp-client');
let sftp = new Client
 sftp.connect(
 host: 'remote_server_iṕ',
 port: 22,
 username: 'username',
 password: 'password'
 ).then(() => 
 let remoteFilePath = '/' + fileName;
 sftp.get(remoteFilePath).then((stream) => 
 let file = './ftp/' + x.name;
 fs.writeFile(file, stream, (err) => 
 if (err) console.log(err);
 );
 sftp.end();
 );
 ).catch((err) => 
 console.log(err, 'catch error');
 );

Use this to close the ftp connection:

sftp.end();
