# OpenAPI Core Library (Typescript)



## What is it?

This project is a library, written in Typescript, containing an assortment of classes

useful to various Apicurio projects.



This project is licensed under the [Apache License 2.0](LICENSE).



## Usage

For details on how to use the library, see the documentation included with the library on

npmjs.com:



  [https://www.npmjs.com/package/@apicurio/core](https://www.npmjs.com/package/@apicurio/core)



This documentation can also be found in this repository here:



  [./module/README.md](https://github.com/Apicurio/apicurio-ts-core/blob/master/module/README.md)



## Building the Library

This section explains how to build, package, test, and publish the library.  If you are a developer

looking to make changes, this is a great place to start.



### Pre-Requisites

In order to do any work with the library you will need to install node.js.  As of the time of this

writing, the versions of node, npm. and yarn used were:



```

$ node -v

v8.11.4

$ npm -v

5.6.0

$ yarn --version

1.13.0

```



Make sure you download and install node/npm/yarn of at least the above versions.



### Clone and Configure

The first thing to do (obviously) is clone the repository.  Once you've cloned the git repository,

you must use yarn (or npm) to install all of the library's dependencies.  It is worth noting that the library

does not have any runtime dependencies, but it has several *build* dependencies (including typescript,

karma, jasmine, etc).  The following commands should help clone and configure:



```

git clone https://github.com/Apicurio/apicurio-ts-core.git

cd apicurio-ts-core

yarn install

```



The result of this should be a number of dependencies downloaded and stored in a new `node_modules`

directory.



### Test the Library

This library uses jasmine+karma for unit testing.  Give it a try by doing this:



```

yarn test

```



You should see a number of unit tests get executed (you may need Google Chrome installed for

this to work).  They should all succeed and you should see a report at the end.



### Releasing a New Version

Once changes have been made and finalized, you're probably going to release a new version

of the library.  This is done by packaging the library into an npm compatible package and

releasing it (into npmjs.com).



#### Modify the Version

The first step is to increase the project's version number.  This can be done by modifing

the `package.json` file:



```json

{

  "name": "@apicurio/core",

  "version": "0.1.4",

  "description": "A library containing some common classes used by various other Apicurio projects.",

  "license": "Apache-2.0"

}

```



Simply edit the `version` property, giving it the next logical value.  If the change is minor,

then modify the patch version.  If it's a more significant release, then modifying the major

or minor number may be appropriate.



#### Create the Package

Next, create the package (intended for release) by using yarn.  The command to create the 

package is below:



```

yarn run package

```



This command will result in a new `dist` directory being created.  Within this directory

you will find a number of files, all of which must be uploaded to npmjs.com as the new 

release of the library.



#### Publish to npmjs.com

Once everything has been packaged, you can simply use yarn/npm to publish the result into

npmjs.com:



```

yarn publish ./dist

```



#### Tag the Release in Git

If everything went well, you have now built, tested, packaged, and released a new version of

the library into npmjs.com for other projects to use.  The final step is to tag the source

code with the version that was just released.  For example, if you have just published version

0.2.4 of the library, you would tag it in the repository with these commands:



```

git tag -a -m 'Release 0.1.4' 0.1.4

git push origin 0.1.4

```



## Contribute Fixes and Features

This project is open source, and we welcome anybody who wants to participate and contribute!



### Get the code

The easiest way to get started with the code is to [create your own fork](http://help.github.com/forking/)

of this repository, and then clone your fork:



```bash

$ git clone [email protected]:/apicurio-ts-core.git

$ cd apicurio-ts-core

$ git remote add upstream git://github.com/Apicurio/apicurio-ts-core.git

```



At any time, you can pull changes from the upstream and merge them onto your master:



```bash

$ git checkout master       # switches to the 'master' branch

$ git pull upstream master  # fetches all 'upstream' changes and merges 'upstream/master' onto your 'master' branch

$ git push origin           # pushes all the updates to your fork, which should be in-sync with 'upstream'

```



The general idea is to keep your 'master' branch in-sync with the 'upstream/master'.



### Track Your Change

If you want to fix a bug or make any changes, please log an issue in the github 

[Issue Tracker](https://github.com/Apicurio/apicurio-ts-core/issues) describing the bug or new 

feature. Then we highly recommend making the changes on a topic branch named with the issue 

number. For example, this command creates a branch for issue #7:



```bash

$ git checkout -b apicurio-ts-core-7

```



After you're happy with your changes and all unit tests run successfully, commit your changes 

on your topic branch. Then it's time to check for and pull any recent changes that were made in

the official repository since you created your branch:



```bash

$ git checkout master         # switches to the 'master' branch

$ git pull upstream master    # fetches all 'upstream' changes and merges 'upstream/master' onto your 'master' branch

$ git checkout apicurio-ts-core-7  # switches to your topic branch

$ git rebase master           # reapplies your changes on top of the latest in master

                              # (i.e., the latest from master will be the new base for your changes)

```



If the pull grabbed a lot of changes, you should rerun the tests to make sure your changes are 

still good.  You can then either [create patches](http://progit.org/book/ch5-2.html) (one file 

per commit, saved in `~/apicurio-ts-core-7`) with:



```bash

$ git format-patch -M -o ~/apicurio-ts-core-7 orgin/master

```



and upload them to the issue, or you can push your topic branch and its changes into your public 

fork repository with:



```bash

$ git push origin apicurio-ts-core-7         # pushes your topic branch into your public fork

```



and [generate a pull-request](http://help.github.com/pull-requests/) for your changes.  The latter

is definitely the preferred mechanism for submitting changes.



The reason we prefer pull-requests is that we can review the proposed changes, comment on them,

discuss them with you, and likely merge the changes right into the official repository.  No muss,

no fuss!



Please try to create one commit per feature or fix, generally the easiest way to do this is 

via [git squash](https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History#Squashing-Commits).

This makes reverting changes easier, and avoids needlessly polluting the repository history with 

checkpoint commits.
