# Application Message Tutorial
|
||||
|
||||
The objective of this tutorial is to demonstrate the use of **qaskx** to build
|
||||
a microservice to provide an application with messages to display in app.
|
||||
|
||||
The messages can be:**
|
||||
* informational
|
||||
* warning
|
||||
* error
|
||||
|
||||
_Let's Start_
|
||||
|
||||
## Pre-requisites
|
||||
|
||||
Before commencing with this tutorial, the following is assumed:
|
||||
* Git installed
|
||||
* Go language installed
|
||||
* **qaskx** installed and setup
|
||||
* Visual Studio Code installed
|
||||
|
||||
You can follow the [Setup Tutorial](../setup/README.md) to perform the
|
||||
pre-requisites.
|
||||
|
||||
## Objective
|
||||
|
||||
The project objective is to create a microservice in Golang to provide
|
||||
messages to an application and along the way demonstrate the **qaskx**
|
||||
fatures by using ```qaskx-cli``` command line tool.
|
||||
|
||||
_Note 1:_ The microservice is a read only service and there is no security
|
||||
implemented on its use. Data is added to the service by adding data files.
|
||||
|
||||
_Note 2:_ This tutorial does not create a remote Github repository for the
|
||||
tutorial.
|
||||
|
||||
## Establish project space
|
||||
|
||||
The command line tool ```qaskx-cli``` is assumed to be in your path, otherwise you will
|
||||
need to specify the full path location to the tool.
|
||||
|
||||
You can always get help for the command line tool by executing
|
||||
```
|
||||
qaskx-cli --help
|
||||
qaskx-cli CMD SUB-CMD --help
|
||||
```
|
||||
|
||||
where ```CMD``` is the command and ```SUB-CMD``` is the sub command.
|
||||
|
||||
Create the project folders and default files. All commands sample are assumed to be
|
||||
in the ```~/projects/qaskx/messages``` unless otherwise stated
|
||||
|
||||
```
|
||||
qaskx-cli generate project --name qaskx-messages --parent ~/projects/qaskx/messages --template template
|
||||
|
||||
cd ~/projects/qaskx/messages
|
||||
```
|
||||
|
||||
Start the OpenAPI specification design using:
|
||||
* Visual Studio Code OR
|
||||
* Apicurtio (?) using Docker
|
||||
|
||||
|
||||
### Editing OpenAPI with Visual Studio Code
|
||||
|
||||
Using VS Code to edit the OpenAPI requires you to know the
|
||||
OpenAPI specification language. Visual renders of the OpenAPI is available
|
||||
in the VS Code marketplace (for example .... )
|
||||
|
||||
Open VS Code to folder ```~/projects/qaskx/messages```
|
||||
|
||||
Open the OpenAPI specification file ```specs/openapi.json``` and observe
|
||||
the base template definition.
|
||||
|
||||
As this tutorial is not about OpenAPI writing, the required OpenAPI
|
||||
has been pre-prepared for you.
|
||||
For this tutorial you can replace the contents of the OpenAPI file
|
||||
with the contents from file [Message OpenAPI](message_openapi.json)
|
||||
|
||||
After copying the contents to VS Code editor for the ```openapi.json``` file,
|
||||
observe the paths and data models.
|
||||
|
||||
### Editing OpenAPI with Apicurito
|
||||
|
||||
Apicurtio requires less knowledge about the OpenAPI specification language
|
||||
because it provides a UI editor. With the editor you need define data models
|
||||
and then the service paths, which use the data models in requests and
|
||||
responses.
|
||||
|
||||
To edit the OpenAPI using _Apicurtio_:
|
||||
* Start Docker if not started
|
||||
* Execute command
|
||||
```
|
||||
docker container run ....
|
||||
```
|
||||
* Start browser session
|
||||
```
|
||||
http://localhost:8080
|
||||
```
|
||||
* Open the OpenAPI file at (or drop it on the Apicurito browser window)
|
||||
```
|
||||
~/projects/qaskx/messages/specs/openapi.json
|
||||
```
|
||||
* The OpenAPI already comes prefiled with some details
|
||||
|
||||
As this tutorial is not about OpenAPI writing, the required OpenAPI
|
||||
has been pre-prepared for you.
|
||||
For this tutorial you can replace the contents of the OpenAPI file
|
||||
with the contents from file [Message OpenAPI](message_openapi.json)
|
||||
by opening the ```source``` tab at the root of the definition.
|
||||
|
||||
After copying the contents to VS Code editor for the ```openapi.json``` file,
|
||||
observe the paths and data models.
|
||||
|
||||
## Generating the server code
|
||||
|
||||
|
||||
|
||||
## Compiling and running
|
||||
|
||||
|
||||
## Postman or Browser
|
||||
|
||||
You can test the micro service by using Postman or using a browser.
