Depends on following libraries: ByteConverter, JavaObject, jServer, Json, jSQL
1681305751507.png


Features:
  1. CRUD based - RESTful Web API (GET, POST, PUT, DELETE)
  2. Front-end (HTML, CSS, JS, Bootstrap)
  3. Support MySQL and SQLite database (Can be modified for MS SQL or SQL Express)
  4. Separate SQL queries file (queries-mysql.ini and queries-sqlite.ini)
  5. Sample database auto-generated for first run (Category and Product tables with dummy data)
  6. Versioning (using ROOT_PATH in config.ini, set as "/" if you don't want versioning)
  7. Auto generated documentation with API test.

How to use:
  1. Copy the "Web API Server (1.16).b4xtemplate" file into B4J Additional Libraries folder.
  2. Open B4J and create a new project with "Web API Server" template. Give your project any name you like, for e.g. WebAPI
  3. Run the project in Debug or Release mode. You will see something like this in the Logs:
    B4X:
    Web API Server (version = 1.16) is running on port 19800
    Open the following URL from your web browser
    http://127.0.0.1:19800/v1/
  4. Copy the URL showed in Logs and open it using your web browser.

5. To connect to MySQL server, go to Objects folder and open "config.ini". Comment the SQLite section and uncomment the MySQL section.​

6. Edit the root password at line #45 (second last line). Save the file.​
7. In B4J project, comment the line '#AdditionalJar: sqlite-jdbc-3.39.3.0 and uncomment the line #AdditionalJar: mysql-connector-java-8.0.30.​
Make sure you are using the correct version of connector.​
B4X:
#Region AdditionalJar
' MySQL connector
#AdditionalJar: mysql-connector-java-8.0.30
' SQLite connector
'#AdditionalJar: sqlite-jdbc-3.39.3.0
#End Region
8. Follow step #3 above.​

Note: "Web API Client.b4xtemplate" is also attached to demonstrate how to consume the Web API using B4A, B4i and B4J

Comments: I try to make this template as compact as possible (remove user table and email function) but it is still big. If you don't like some features, just remove them. 😄

Web API Server - v1.16 beta 1 (Beta.zip attached in post #1)
Similar to Web API Template 2.0, it is now less confusing by using #Desc and #Elements for documentation

Note: This is a breaking update which causes B4X Web API Client not working (due to changes in Handler name to plural)

    #End region
    Try

        Dim strSQL As String = Main.queries.Get("SELECT_CATEGORY_BY_ID")
        Dim res As ResultSet = con.ExecQuery2(strSQL, Array As String(cid))
        Do While res.NextRow
            Dim Map2 As Map
            Map2.Initialize
            For i = 0 To res.ColumnCount - 1
                Select res.GetColumnName(i)
                    Case "id"
                        Map2.Put(res.GetColumnName(i), res.GetInt2(i))
                    Case Else
                        Map2.Put(res.GetColumnName(i), res.GetString2(i))
                End Select
            Next
            List1.Add(Map2)
        Loop
        res.Close
       
        If List1.Size > 0 Then
            HRM.ResponseCode = 200
        Else
            HRM.ResponseCode = 404
            HRM.ResponseError = "Category Not Found"

Hi
Is it already finished or does the version of the Web Api server 2.5 with the Dashboard exist?
Please start a new thread.
This is Web API Server template version 1.x but you are seems asking about version 2.x
If you are looking for Web API Server template 2.x then you can go to top of the first post, there is a link to that thread.
