Spine Ftp Client

Yet another implementation of ftp client protocol. Written in pure typescript. Fast, stable & reliable. Easy extensible.

Requirements

• node.js - v. 4.x

Installation

npm install spine-ftp

Examples

• Get a directory listing of the current remote working directory (list files)

import { FtpClient } from 'spine-ftp';

const client = await FtpClient.connect({

    host: "127.0.0.1",
    port: 21,
    user: "anonymous",
    password: "anonymous"
    timeout: 1000
});

const files = await client.getFiles();

await client.disconnect();

• Download remote file & save to local fs

import { FtpClient } from 'spine-ftp';

const client = await FtpClient.connect({

    host: "127.0.0.1",
    port: 21,
    user: "anonymous",
    password: "anonymous"
    timeout: 1000
});

// download to local file `local.txt` and overwrite if exists
await client.download("foo.txt", "local.txt", true);
await client.disconnect();

• Upload local file to the server

import { FtpClient } from 'spine-ftp';

const client = await FtpClient.connect({

    host: "127.0.0.1",
    port: 21,
    user: "anonymous",
    password: "anonymous"
    timeout: 1000
});

// upload to server with remote name `remote.txt`
await client.upload("foo.txt", "remote.txt");
await client.disconnect();

• Check if file exists on server

import { FtpClient } from 'spine-ftp';

const client = await FtpClient.connect({

    host: "127.0.0.1",
    port: 21,
    user: "anonymous",
    password: "anonymous"
    timeout: 1000
});

const exists = await client.fileExists("foo.txt");
client.disconnect();

TODO

Feel free to commit:

• Full code coverage in tests
• Some missing FTP commands eg. append
• Secure connection
