# Swagger project for SDRangel
|
|
|
|
<h1>What is Swagger?</h1>
|
|
|
|
Swagger is an open source software framework backed by a large ecosystem of tools that helps developers design, build, document, and consume RESTful Web services. [Link to Swagger website](https://swagger.io/)
|
|
|
|
Swagger is used to design the SDRangel web API. You will find the Swagger framework for SDRangel here.
|
|
|
|
<h1>Install Swagger</h1>
|
|
|
|
Uses `apt-get` package manager (Ubuntu, Debian). Use your distribution package manager for other distributions
|
|
|
|
```shell
|
|
sudo apt-get install npm
|
|
sudo npm install -g swagger
|
|
```
|
|
|
|
install Node.js 6.x on Ubuntu 16.04 :
|
|
|
|
```shell
|
|
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
|
|
sudo apt-get install -y nodejs
|
|
```
|
|
Install http-server a lightweight web server to serve included files
|
|
|
|
```shell
|
|
sudo npm install -g http-server
|
|
```
|
|
|
|
<h1>Work with Swagger</h1>
|
|
|
|
<h2>Edit files with Swagger</h2>
|
|
|
|
All commands are relative to this directory (where the README.md is)
|
|
|
|
Firstly start a node server to serve files
|
|
|
|
```shell
|
|
http-server --cors .
|
|
```
|
|
|
|
To start on a different port than 8080 that may be busy use the `-p` option:
|
|
|
|
```shell
|
|
http-server -p 8081 --cors .
|
|
```
|
|
|
|
Then in the directory where this README.md is start the swagger editor
|
|
|
|
```shell
|
|
swagger project edit
|
|
```
|
|
|
|
<h2>Mocking</h2>
|
|
|
|
Write controllers for mocking in `api/mocks/`
|
|
|
|
Run the server in mock mode:
|
|
|
|
```shell
|
|
swagger project start -m
|
|
```
|
|
|
|
<h2>Generating code</h2>
|
|
|
|
<h3>Installation</h3>
|
|
|
|
The released code generator is presently creating memory leaks for the Qt5/cpp generated code. A fixed version is available [here](https://github.com/etherealjoy/swagger-codegen/tree/qt5cpp_rework_antis81_patch-1).
|
|
|
|
So you will have to clone this repository and checkout the `qt5cpp_rework_antis81_patch-1` branch. Then follow the build instructions which are very simple when using maven:
|
|
|
|
```shell
|
|
sudo apt-get install maven # do this once to install maven
|
|
cd swagger-codegen
|
|
export JAVA_HOME=/opt/install/jdk1.8.0_172 # Example JDK change to your own
|
|
mvn clean package # let it compile...
|
|
mkdir -p /opt/install/swagger/swagger-codegen
|
|
cp modules/swagger-codegen-cli/target/swagger-codegen-cli.jar /opt/install/swagger
|
|
```
|
|
|
|
Then in the `/opt/install/swagger/` directory write a little `swagger-codegen` shell script to facilitate the invocation. For example:
|
|
|
|
```shell
|
|
#!/bin/sh
|
|
/opt/install/jdk1.8.0_74/bin/java -jar /opt/install/swagger/swagger-codegen-cli.jar ${*}
|
|
```
|
|
Give it execute permissions:
|
|
|
|
```shell
|
|
chmod +x /opt/install/swagger/swagger-codegen
|
|
```
|
|
|
|
Then invoke the generator with `/opt/install/swagger/swagger-codegen <commands>`
|
|
|
|
<h3>Code generation</h3>
|
|
|
|
Do not forget to start the http server for includes as described before for the editor.
|
|
|
|
Eventually to generate the code for Qt5 in the code/qt5 directory do:
|
|
|
|
```shell
|
|
/opt/install/swagger/swagger-codegen generate -i api/swagger/swagger.yaml -l qt5cpp -c qt5cpp-config.json -o code/qt5
|
|
```
|
|
|
|
The language option `-l` allows to generate code or documentation in a lot of languages (invoke the command without any parameter to get a list). The most commonly used are:
|
|
|
|
- html2: documentation as a single HTML file pretty printed. Used to document the API in code/html2
|
|
- python: Python client
|
|
- angular2: Typescript for Angular2 client
|
|
|
|
The configuration option `-c` lets you specify a configuration file which is in JSON format and for which the key, value pairs are documented in the config-help of the specified codegen language. For example the following command will return the possible key values for Qt5 C++ generator:
|
|
|
|
```shell
|
|
/opt/install/swagger/swagger-codegen config-help -l qt5cpp
|
|
```
|
|
|
|
The following configuration files have been defined for generation in the SDRangel context:
|
|
|
|
- `qt5cpp-config.json` for Qt5/C++
|
|
- `html2-config.json` for HTML2
|
|
- `python-config.json` for Python
|
