Typescript

A library of re-usable TypeScript components.

Installation

To install this, simply run:

npm install @pod-point/typescript

Usage

This package contains a HTTP client, an abstract HTTP repository & service class, an abstract model class and model factories.

Client

Create a client instance to make http requests.

// path/to/client
import { Client } from '@pod-point/typescript';

export default new Client(...args);

Repositories & Services

Create and use a repository to wrap a RESTful API endpoint and handle the json as a model rather than a plain old JavaScript object.

// path/to/ExampleRepository
import { Repository } from '@pod-point/typescript';
import ExampleModel from 'path/to/ExampleModel';

export default class ExampleRepository extends Repository<ExampleModel> {
    //

// path/to/anywhere
import ExampleRepository from 'path/to/ExampleRepository';
import client from 'path/to/client';

const exampleRepository = new ExampleRepository(client);

Models & Factories

Create model factories to generate:

• fake model instances
• fake objects representing a models attributes
• fake objects representing a models payload

// path/to/ExampleModelFactory
import { Factory } from '@pod-point/typescript';
import ExampleModel from 'path/to/ExampleModel';
import ExampleModelAttributes from 'path/to/ExampleModelAttributes';

export default class ExampleModelFactory extends Factory<ExampleModel, ExampleModelAttributes> {
    //

import { ExampleModelFactory } from 'path/to/ExampleModelFactory';

const exampleModelFactory = new ExampleModelFactory();
const fakeExampleModelAttributes = exampleModelFactory.attributes();
const fakeExampleModel = exampleModelFactory.model();

Overrides can be passed into all of these methods, and there is also a method available to generate any of these objects in a pre-defined "state".

This is styled on the Laravel factories.

Example:

import { ExampleModelFactory } from 'path/to/ExampleModelFactory';

const exampleModelFactory = new ExampleModelFactory();
const exampleModel = exampleModelFactory.states(['deleted']).model();

In the example above we have applied the "deleted" state before generating the model, this would basically apply some pre-defined overrides to the fake attributes.

Development

Testing

This package uses jest. To run the test suites for this project, run the following command:

npm run test

Releases

This package is distributed via NPM and published automatically by Travis when creating a tagged commit. This can be done in one of 2 ways, see below. After you did this, please don't forget to draft your new release on the GitHub Releases page!

1. Pre-merge via the CLI

Before merging your PR following code review & QA, run the following commands to update the package version and create a new release/tag.

npm version <major|minor|patch|prerelease>
git push && push --tags

If you forget to do this before merging, this is not a problem, just create a new branch from master and run these same commands, remembering to open and merge a PR for this branch so that the package.json file is updated, alternatively, see option 2.

2. Post-merge via code & GitHub

After merging your code changes, create a new branch/PR from master and update the package version in package.json to whatever you wish the next release to be.

Before merging this PR, create a release via GitHub with a tag version to match this package version number, this will trigger the tagged commit and in turn the automatic deployment to NPM.
