Reconstruction plan
DocHub project was relatively high in the clouds and star GitHub code received, it is because most people hit the project's needs, and front page design is relatively simple and good-looking, and the user experience is also acceptable.
But the truth is that the code is written in Java, this really is not self-deprecating. Although I have made great efforts to optimize, but a reasonable database design and non-standard code writing, leading to subsequent extensions and code maintenance difficult.
So, I decided to overthrow the entire project to reconstruct. Existing branch will continue to maintain and repair Bug, but will not add new features. Will be reconstructed on the new branch, for incompatibility issues, will be a migration tool to help migrate from an older version to the new version of the reconstruction up.
Services Architecture
Full service architecture diagram below, according to the amount of one million IP access to the design.

- The front and rear ends DocHub completely separate aspect, a set of API interface, for APP PC and distal ends and a mobile use applets
- Document conversion service server resources consuming, computationally intensive part of the function into a separate document conversion service
moredoc(i.e.魔刀), so as to be independently deployed on another server CloudStoreMediation is a cloud storage service, support will store documents and other data files to the major cloud storage.
moredoc (Tin document conversion services)

moredocConversion principle and technical configuration, as shown in FIG.
The service will support all office document types and document types such as epub into pictures that can be displayed on the front page to provide users to read.
Existing dochublibrary systems are currently dependent on document conversion software is basically the top of these (except pdftohtmlex).
Because this part of the software installation and deployment of, for white users and users of different systems, more complex, so the whole into moredocafter document conversion services, the whole will be packed into dockera container, moredocprovided only resetful document conversion interface to dochubmake the call.
Technology stack
Distal aspect mainly used Vue, taking into account the SEOneeds, with Nuxtthe use of, using the UI ElementUI.
End the use of mobile uni-appsolutions, once developed, multi-terminal distribution.
Back-end selection of Golanguage, as group of friends asked why not PHPand Python...
I also did three years PHP development, finally escape out, and trying to cheat me back, how could ... Pythonthen, the company will write the script doing the operation and maintenance, with no truly had to develop a product, this language or unskilled.
Therefore, considering the chosen language Go, Go grammar simplicity, performance and development efficiency are high, then compiled into a binary executable file, the server will be able to direct throw to run, you do not need to rely on the installation environment, simple to deploy.
Reconstruction period
I would like to develop at their own pace, as is done in the spare time to develop, so development cycle for at least six months or more.
