## Usage
|
||||
There are 2 parts to this package: CSV to JSON serialization and JSON to CSV serialization. The module exposes 2 methods to fullfil these: `parse` and `unparse` respectively.
|
||||
|
||||
To `parse` CSV file and convert it to JSON use `parse` method, e.g.:
|
||||
```js
|
||||
const {parse} = require('@tryghost/members-csv');
|
||||
|
||||
const mapping = {
|
||||
email: 'csv_column_containing_email_data',
|
||||
name: 'csv_column_containing_names_data'
|
||||
}
|
||||
const membersJSON = await parse(csvFilePath, mapping);
|
||||
```
|
||||
|
||||
`csvFilePath` - is a path to the CSV file that has to be processed
|
||||
`mapping` - optional parameter, it's a hash describing custom mapping for CSV columns to JSON properties
|
||||
|
||||
Example mapping for CSV having email under `correo_electronico` column would look like following:
|
||||
```
|
||||
{
|
||||
email: 'correo_electronico'
|
||||
}
|
||||
```
|
||||
|
||||
To `unparse` JSON to CSV compatible with members format use following:
|
||||
```js
|
||||
const {unparse} = require('@tryghost/members-csv');
|
||||
|
||||
const members = [{
|
||||
email: 'email@example.com',
|
||||
name: 'Sam Memberino',
|
||||
note: 'Early supporter'
|
||||
}];
|
||||
|
||||
const membersCSV = unparse(members);
|
||||
|
||||
console.log(membersCSV);
|
||||
// -> "id,email,name,note,subscribed_to_emails,complimentary_plan,stripe_customer_id,created_at,deleted_at,labels\r\n,email@example.com,Sam Memberino,Early supporter,,,,,,"
|
||||
```
