@memberjunction/core v1.2.0
@memberjunction/core
The @memberjunction/core
library provides a comprehensive interface for accessing and managing metadata within MemberJunction, along with facilities for working with entities, applications, and various other aspects central to the MemberJunction ecosystem. This library primarily exports a Metadata
class which acts as the gateway to many functionalities.
Installation
npm install @memberjunction/core
```markdown
## Usage
### Importing the Library
```javascript
import { Metadata } from '@memberjunction/core';
Working with the Metadata Class
The Metadata
class is a crucial part of this library, providing access to a wide array of metadata, instantiating derived classes of BaseEntity
for record access and manipulation, and more.
Instantiating the Metadata Class
const md = new Metadata();
Refreshing Cached Metadata
await md.Refresh();
Getting Applications, Entities, and Other Info
const applications = md.Applications;
const entities = md.Entities;
const currentUser = md.CurrentUser;
// ... and so on for other properties
Helper Functions
// Get Entity ID from name
const entityId = md.EntityIDFromName('EntityName');
// Get Entity name from ID
const entityName = md.EntityNameFromID(1);
// ... and other helper functions as defined in the class
Working with Datasets
// Example: Getting a dataset by name
const dataset = await md.GetDatasetByName('DatasetName');
This is a brief overview of how to interact with the Metadata
class. The methods and properties provided by the Metadata
class serve as a bridge to access and manage data in a structured and coherent manner within the MemberJunction ecosystem.
RunView and RunViewParams
The @memberjunction/core
library also provides a mechanism for running either a stored or dynamic view through the RunView
class. The parameters for running these views are specified through the RunViewParams
type.
Importing Necessary Classes and Types
import { RunView, RunViewParams } from '@memberjunction/core';
Using RunViewParams
RunViewParams
is a type that helps in specifying the parameters required to run a view. The fields in RunViewParams
allow you to specify whether you want to run a stored or dynamic view, and provide additional filters, sorting, and other options. Here's an example of how you might create a RunViewParams
object:
const params: RunViewParams = {
ViewName: 'MyView',
ExtraFilter: 'Age > 25',
OrderBy: 'LastName ASC',
Fields: ['FirstName', 'LastName'],
UserSearchString: 'Smith'
// ... other optional properties as needed
};
Using the RunView Class
The RunView
class provides a method to run a view based on the provided parameters.
Instantiating the RunView Class
const rv = new RunView();
Running a View
const result = await rv.RunView(params);
In this example, params
is an object of type RunViewParams
which contains the information necessary to run the view. The RunView
method will return a Promise<RunViewResult>
which will contain the result of running the view.
