Introduction

`

Docs

Find all the details for @supercharge/method-missing in the extensive Supercharge docs.

Usage

Using @supercharge/method-missing is pretty straightforward. The package exports a class that you must extend in your implemented class. Then, add a __call(methodName, args) method to your class. The __call method allows you to handle all calls for methods that are not existent in your class.

I guess an example clears things up:

`js
const MethodMissing = require('@supercharge/method-missing')

class QueryInterface extends MethodMissing {
/**
* Creates an instance wrapping the Sequelize queryInterface instance.
*
* @param {QueryInterface} queryInterface
*/
constructor (queryInterface) {
super()

this.queryInterface = queryInterface
}

/**
* Determine whether the given column already exists in the given table.
*
* @param {String} table
* @param {String} column
*
* @returns {Boolean}
*/
async hasColumn(tableName, columnName) {
const description = await this.queryInterface.describeTable(tableName)

return !!description[columnName]
}


/**
* Pass through all calls to the original query interface.
*
* @param {String} methodName
* @param {Array} args
*
@returns {}
*/
__call(methodName, args) {
return this.queryInterfacemethodName
}
}
`
