A collection of tips to assist developers to configure their local workstation setup environment for FOLIO development.
- Configuration for repository usage
- Coding style
- Update git submodules
Assume already doing other development, so know how to keep the operating system up-to-date, know its quirks, know how to use the various package managers. So this document will not go into detail about that.
FOLIO modules can be developed in any suitable programming language.
The FOLIO-Sample-Modules explains about module development. The various Stripes documentation explains user-interface development. Those also have more notes about setting up and managing the local development environment.
Note that some parts of the development environment could be handled using folio-ansible (virtual machines using Vagrant and Ansible).
Otherwise the development environment would need the following fundamental tools:
- Apache Maven (3.3+) and Java (8+) – For building and deploying Okapi and some server-side modules.
- Node.js (6+) – For Stripes and for some modules.
- Docker – Recommended method for deployment.
As each FOLIO component can utilise whatever suite of appropriate tools, refer to its requirements and notes to assist with setup.
Occasionally it becomes necessary to specify minimum versions of some tools:
- Java: 1.8.0-101
Configuration for repository usage
FOLIO utilizes the Nexus OSS Repository Manager to host Maven artifacts and NPM packages for FOLIO projects. Docker images are the primary distribution model for FOLIO modules.
An overview and usage configuration details are provided, see Build, test, and deployment infrastructure.
Style guidelines and configuration
Some modules have linter and code-style tools implemented as part of their build process. Some modules provide configuration files to assist code management tools.
Use EditorConfig for consistent whitespace
Many FOLIO repositories have a
.editorconfig configuration file at their top level. This enables consistent whitespace handling.
Refer to EditorConfig.org which explains that some text editors have native support, whereas others need a plugin.
Consult its documentation for each plugin. Note that some do not handle all EditorConfig properties.
In such cases refer to the documentation for the particular text editor, as it might have its own facilities.
For example, the Java text editor in Eclipse has its own configuration for
Update git submodules
Some FOLIO repositories utilize “git submodules” for sections of common code.
For example, each
mod-* module and
raml-module-builder include the “raml” repository as a git submodule as its
Note that when originally cloning a repository, use ‘git clone –recursive …’ Some git clients do not. If you then have an empty “raml-util” directory, then do ‘git submodule update –init’.
Thereafter updating that submodule is deliberately not automated, so that we can ensure a stable build when we git checkout in the future.
So when an update is needed to be committed, do this:
cd mod-configuration (for example) git submodule foreach 'git checkout master && git pull origin master' git commit ...
Now when people update their local checkout, then some git clients do not automatically update the submodules. So they need to follow with ‘git submodule update’.
This part can be automated with client-side git hooks. Create the following two shell scripts:
using this content:
#!/bin/sh git submodule update
and make them executable: ‘chmod +x post-checkout post-merge’
Now subsequent updates will also update the submodules to their declared revision.
