velo-sync

The velo-sync tool imports data into a collection on a Wix site. The tool syncs database items and media files (images, videos, audio files or documents) making them available in a wix data collection.

velo-sync supports the following operations:

Command	Data	Description
import	Doesn't include a `keyField`	Each data item is added as a new item in the collection
import	Includes a `keyField`	Existing items with a matching `keyfield` are updated. If no item with a matching `keyfield` exists, a new item is added top the collection
sync	Doesn't include a `keyField`	Similar to import without `keyField`, but removes all other items from the collection
sync	Includes a `keyField`	Similar to import with a `keyField`, but removes all other items from the collection

The velo-sync application can be used in two different ways:

As a CLI Application to import and sync CSV files and referenced media
As an API to import JavaScript objects and referenced media

Usage as a CLI Application

To use the velo-sync CLI Application, you need to:

Prepare your data
Prepare your site
Prepare the app

Prepare your Data

1. Prepare the CSV file

The data to be imported or synced should be formatted as a standard CSV file, that includes the following conventions:

A header line with field names.
Any field that includes a comma (,) or a new line should be enclosed with quotes (").
Any field values that include quotes should escape the quotes with double quotes ("").

The following is an example of a CSV file:

Image,Artist,Location,Description,ID,Name

The piece is over two storeys up and represents a woman falling with a trolley from the top of a building. Banksy’s aim was to point out the dangers of consumerism.  The mural was painted in November 2011 in broad daylight. A scaffolding and a tarpaulin were used to make sure nobody caught the artist red-handed. “Shop Till You Drop” is still visible and quite damaged.",0560c783-f374-44f6-b318-908d6de77816, Shop Till You Drop

The mural, painted in 2009, represents a city worker covering the work of another graffiti artist painted in 1985 with grey wallpaper.  This wall became the battleground of a graffiti war between Banksy and the deceased London graffiti legend King Robbo. Shortly after, Robbo struck back and covered Banksy’s piece on the pretext that he broke the underground code of conduct. The wall undergone eight other modifications from both artists. The feud stopped when King Robbo was hospitalised for life-threatening head injuries. When Banksy heard about King Robbo’s serious health condition, he painted an ode to Robbo’s original graffiti piece. As a tribute to Robbo, the mural was restored to its original form with slight changes.",414c339e-0300-44b9-b8a4-376d8f0acbca, Graffiti Painter

Note: More examples of CSV files can be found in the example-datasets folder.

2. Prepare the schema file

The schema file describes the values in the CSV file. It maps the values in the CSV file to the correct field types in your site's collection.

An example schema file:

{
  "keyField": "ID",
  "fields": {
    "Image": "Image",
    "Artist": "Reference",
    "Location": "string",
    "Description": "string",
    "ID": "string",
    "Name": "string"
  }
}

The schema file has two main properties:

keyField - [optional] A value in the CSV file used to identify existing data in the collection. If the collection has an item whose _id matches the keyField value, the existing item is updated with the new values from the CSV file. If no item with that _id exists, a new item is added to the collection.
fields - The fields in the CSV file that match the fields in your site's collection. The property name is the name of the field in your collection and its value is the field type.

* For media and files, the upload process supports 4 different formats of file references:

Relative file location - The file will be uploaded to Wix and replaced with a Wix URL (wix:image, etc.). The file location is relative to the CSV file.
File URL - The file will be uploaded to Wix and replaced with a Wix URL.

Prepare your site

To enable velo-sync on a Wix site:

Add an http-functions.js file to your Backend files.
Copy the contents of http-functions.js into the http-function.js file.
Define a secret named velo-sync in the Secret Manager (Settings > Secrets Manager), and give it a unique value.
Publish the site so that the http-functions.js file will be deployed to the site.

Prepare the application

Make sure you have node.js version v12 or above installed. From the command line, run the application with the following command. The app usage should be displayed:

➜ npx velo-sync
npx: installed 115 in 8.748s
Usage: 
 npx velo-sync [command] [options...]

Commands:
  init          generates a config file for the import / export / sync process
  is-alive      tests the config and the connection to the site
  sync          runs the sync process
  import        runs an import process

1. init the connection to your Wix site

Run npx velo-sync init and follow the instructions:

➜ npx velo-sync init
npx: installed 115 in 7.133s
hello to velo-sync init
what is the url of the site homepage? https://dommain.com
what is the velo-sync secret? <your secret>

The init command creates a config.json file with the connection to your site.

2. Test the connection

The is-alive command is used to verify the connection to your site using the config.json file generated by the init command.

➜ npx velo-sync is-alive
npx: installed 115 in 7.64s
checking if the API for site https://domain.com is alive...
API of site https://domain.com is working and alive!!!

3. Run the sync process in Dry Run mode

You can optionally run the sync or import commands in dry-run mode. In Dry Run mode, no data is imported or updated on your site. The sync process reads all the data and all the referenced files and reports any potential issues.

Dry Run detects any data parsing or file reference issue.

The sync and import commands require the following parameters:

-f - the CSV file to import
-c - the name of the collection to import data into
-s - the schema file
--dry - run in dry-run mode.

4. Run the sync process

You can now run the sync or import commands. import will import the data and files, while sync will also remove existing items from the collection.

The sync and import commands require the following parameters:

-f - the CSV file to import
-c - the name of the collection to import data into
-s - the schema file

Example run:

➜ npx velo-sync import -f Art.csv -c Items -s Art-schema.json
npx: installed 115 in 7.349s
0:0:0    starting import Art.csv to Items
0:0:0      check update state batch 0 with 16 items

0:0:3      batched items: 16
0:0:3      check update state: 16
0:0:3      up to date items: 13
0:0:3      update: 3
0:0:3    completed importing Art.csv to Items

Usage as an API

velo-sync can be used directly as an API. To use it as an API, import the createDataSync function from the npm package.

import {createDataSync, LoggingStatistics, LoggerRejectsReporter} from 'velo-sync';

async function run() {
  // The data to import to your site
  let data = [...];
  // The collection name on your site
  let collection = 'items'; 
  // Your connection configuration
  let config = { 
    "siteUrl": "https://domain.com",
    "secret": "<your secret>"
  };
  // Your data's schema
  let schema = { 
    "keyField": "ID",
    "fields": {
      "Image": "Image",
      "Artist": "Reference",
      "Location": "string",
      "Description": "string",
      "ID": "string",
      "Name": "string"
    }
  };
  // Statistics reporter
  let stats = new LoggingStatistics(); 
  // Rejects reporter
  let rejectsReporter = new LoggerRejectsReporter(stats); 
  // Base folder for resolving relative filenames
  let filesFolder = './'; 
  // implementation of FileUploadCache, based on local sqlite database
  let uploadFileCache = new SQLiteFileUploadCache('./.upload-cache.sqlite.db')
  // if a local file cache is not needed, we can use the NoopFileUploadCache implementation 
  //let uploadFileCache = new NoopFileUploadCache();
  // dry run - do not update data on the wix site side
  let dryRun = false;

  // open sqlite cache 
  await uploadFileCache.open();
  try {
    let dataSync = createDataSync(collection, config, schema, stats, filesFolder,
            rejectsReporter, uploadFileCache, dryRun)

    // Add the items to the data sync and if the internal queues are full, wait for space for the next item
    for (item of data)
      await dataSync.handleItem(item);

    // Mark that there are no more items to be imported, to flush all internal buffers
    dataSync.noMoreItems();
  
    // Wait for the sync process to complete
    await dataSync.done();
  }
  finally {
    // close and flush the sqlite file
    await uploadFileCache.close();
  }
}
