Install

via NPM:
``
$ npm install --save-dev mysql-import
`
Via Github:
`
git clone https://github.com/Pamblam/mysql-import.git
`

TLDR:

`js
const host = 'localhost';
const user = 'root';
const password = 'password';
const database = 'mydb';

const Importer = require('mysql-import');
const importer = new Importer({host, user, password, database});

// New onProgress method, added in version 5.0!
importer.onProgress(progress=>{
var percent = Math.floor(progress.bytes_processed / progress.total_bytes * 10000) / 100;
console.log(${percent}% Completed);
});

importer.import('path/to/dump.sql').then(()=>{
var files_imported = importer.getImported();
console.log(${files_imported.length} SQL file(s) imported.);
}).catch(err=>{
console.error(err);
});
`


Methods

$3

The constructor requires an object with a host, user, and password parameter. Passing in a database parameter is optional.

$3

Get an array of files imported.

$3

Set the encoding to use when reading import files. Supported arguments are: utf8, ucs2, utf16le, latin1, ascii, base64, or hex.

$3

Set or change the database to import to.

$3

(New in v. 5.0!) - Set a callback to be called as the importer processes chunks of the dump file. Callback is provided an object with the following properties:

- total_files: The total files in the queue.
- file_no: The number of the current dump file in the queue.
- bytes_processed: The number of bytes of the file processed.
- total_bytes: The size of the dump file.
- file_path: The full path to the dump file.

$3

(New in v. 5.0!) - Set a callback to be called after each dump file has completed processing. Callback is provided an object with the following properties:

- total_files: The total files in the queue.
- file_no: The number of the current dump file in the queue.
- file_path: The full path to the dump file.
- error: If there was an error, the error object; if no errors, this will be null.

$3

Import an .sql file or files into the database. This method will take...

- Any number of paths to individual .sql files.
`
importer.import('path/to/dump1.sql', 'path/to/dum2.sql')
`
- Any number of paths that contain any number of .sql files.
`
importer.import('path/to/mysqldumps/')
`
- Any number of arrays containing either of the above.
`
importer.import(['path/to/dump.sql', 'path/to/dumps/'])
`
- Any combination of any of the above.

$3

Disconnects the connection. If graceful` is switched to false it will force close any connections. This is called automatically after files are imported so typically this method should never be required.
