PoC Assembly - TC API - Generate Source Code Image API

Project Overview

TopCoder and the TopCoder community have worked hard to get the platform to its currently level of maturity, but we're far from done. It's time to take the platform to the next level. TopCoder is going to start taking some steps to open up the platform API to the outside and community developers so they could incorporate it in their websites, applications or build their own applications (web, mobile or desktop).

The ultimate goal is to open up and build an "API" that is targeting all different type of audiences - Software and Studio Competitors, SRM/MM competitors, Copilots, Admins and TopCoder partners - each audience will have different interests and usages of the API, so it will be a huge project and we need to make sure that we are in the right direction from the beginning.

Competition Task Overview

 Currently, we have provided installation guide for different environments, like CentOS 6.x, Ubuntu, Mac OS and Windows. please check https://github.com/cloudspokes/tc-api/wiki

The updated code must still deploy and work on heroku - any submission which can't be deployed on heroku successfully will be failed in screening phase - primary reviewer must check this.

The implementation will base on the node.js version of TC platform API - https://github.com/cloudspokes/tc-api. Please follow the existing actionhero pattern for your development.

Generate Source Code Image API

This is a new API, the route will be like /:apiVersion/src2image

Following are the general requirements for this API.

1. It will take a code parameter, which contains the source code to generate.

2. due to the limitation of GET method for parameter value length, POST method will be used for this API.

3. The API will take the following procedure to generate image.

• It will use highlight to generate the html code that will highlight the source code.
• After getting the html code, it will use node-wkhtml to generate the source code image.

4. For testing, please test that the API can properly handle languages at least C++, Java, Python, C# and VB.NET, the source code can be grabbed at http://community.topcoder.com/longcontest/stats/?module=MatchList or http://community.topcoder.com/tc?module=MatchList

5. Please generate a report about the speed test for different sample source code generation time.

Update API Doc

the apiary.apib  should be updated to describe the new API.

Standarize Query Naming Convension

we like to use the underscore approach in all SQL queries under the queries directory, please follow same approach.

Notes, for the JSON data returned, we will use camelCase approach.

Testing

The API Framework supports tests. Use supertest with mocha. Don't install mocha globally.

you must use mocha BDD style (which is the default), within that, you can optionally use chai.

Please check Test Creation Guide page in wiki

Code Format

All code must pass jslint. You may use "nomen: true".

Winner Only

Winner will create pull request against the main github repo in final fix phase and help merge with master. The changed files should be unix style, you can use dos2unix command to convert it before commiting.

Virutal Machines (VMs)

To use the Arena VM, please follow http://apps.topcoder.com/wiki/display/docs/Competition+Engine+VM+Setup

VM specific information is found here: http://www.topcoder.com/wiki/display/docs/VM+Image+2.5

Upon registration as a submitter or reviewer you will need to request a VM based on the TopCoder systems image. The VM will be active through aggregation review, after which it will be terminated except for the winner's and the reviewers'. To request your image, please post in contest forum.

Before requesting your VM, you need to ensure that you have an SSH key created and in your member profile. Instructions to do so are here: http://www.topcoder.com/wiki/display/projects/Generate+SSH+Key, and instructions to connect afterwards are here: http://www.topcoder.com/wiki/display/projects/Connect+Using+SSH+Key.

Please realize that VMs are currently issued manually. We make every attempt to issue the VM as soon as it is requested, however, there may be delays of up to 12 hours depending on time of day when you request. We encourage everyone to request a VM as soon as possible to minimize any such delays.
