   5 ## Summary
   6
   7 Simple [node.js](https://nodejs.org/) software to simulate a set of charging stations based on the OCPP-J 1.6 protocol as part of SAP e-Mobility solution.
   8
   9 ## Prerequisites
  10
  11 Install the [node.js](https://nodejs.org/) LTS runtime environment:
  12
  13 ### Windows
  14
  15 - [Chocolatey](https://chocolatey.org/):
  16
  17 ```powershell
  18 choco install -y nodejs-lts
  19 ```
  20
  21 ### MacOSX
  22
  23 - [Homebrew](https://brew.sh/):
  24
  25 ```shell
  26 brew install node@16
  27 ```
  28
  29 ### GNU/Linux:
  30
  31 - [NodeSource](https://github.com/nodesource/distributions) Node.js Binary Distributions for version 16.X
  32
  33 ## Installation
  34
  35 In the repository root, run the following command:
  36
  37 ```shell
  38 npm install
  39 ```
  40
  41 ## Initial configuration
  42
  43 Copy the configuration template file [src/assets/config-template.json](src/assets/config-template.json) to [src/assets/config.json](src/assets/config.json).
  44 Copy the authorization RFID tags template file [src/assets/authorization-tags-template.json](src/assets/authorization-tags-template.json) to [src/assets/authorization-tags.json](src/assets/authorization-tags.json).
  45
  46 Tweak them to your needs by following the section [configuration files syntax](README.md#configuration-files-syntax).
  47
  48 ## Start
  49
  50 To start the program, run: `npm start`.
  51
  52 To start the program with a UI controller, run: `npm run start:server`.
  53 Then, start/stop the simulator by going to `https://<hostname:port>` in a browser. Localhost port will default to 8080. For Cloud Foundry, the port is assigned based on the `process.env.PORT` environment variable.
  54
  55 ## Configuration files syntax
  56
  57 All configuration files are in the JSON standard format.
  58
  59 **Configuration files locations**:
  60
  61 - charging stations simulator configuration: [src/assets/config.json](src/assets/config.json);
  62 - charging station configuration templates: [src/assets/station-templates](src/assets/station-templates);
  63 - charging station configurations: [dist/assets/configurations](dist/assets/configurations);
  64 - charging station RFID tags lists: [src/assets](src/assets).
  65
  66 The charging stations simulator's configuration parameters must be within the `src/assets/config.json` file. A charging station simulator configuration template file is available at [src/assets/config-template.json](src/assets/config-template.json).
  67
  68 All charging station configuration templates are in the directory [src/assets/station-templates](src/assets/station-templates).
  69
  70 A list of RFID tags must be defined for the automatic transaction generator with a default location and name: `src/assets/authorization-tags.json`. A template file is available at [src/assets/authorization-tags-template.json](src/assets/authorization-tags-template.json).
  71
  72 **Configuration files hierarchy and priority**:
  73
  74 1. charging station configuration: [dist/assets/configurations](dist/assets/configurations);
  75 2. charging station configuration template: [src/assets/station-templates](src/assets/station-templates);
  76 3. charging stations simulator configuration: [src/assets/config.json](src/assets/config.json).
  77
  78 The charging stations simulator have an automatic configuration files reload feature at change for:
  79
  80 - charging stations simulator configuration;
  81 - charging station configuration templates;
  82 - charging station authorization RFID tags lists.
  83
  84 But the modifications to test have to be done to the files in the build target directory [dist/assets](dist/assets). Once the modifications are finished, they have to be reported or copied to the matching files in the build source directory [src/assets](src/assets) to ensure they will be taken into account at next build.

 246 ### Charging station configuration
 247
 248 **dist/assets/configurations/\<hashId\>.json**:
 249
 250 The charging station configuration file is automatically generated at startup from the charging station configuration template file and is persistent.
 251
 252 The charging station configuration file content can be regenerated partially on matching charging station configuration template file changes. The charging station serial number is kept unchanged.
 253
 254 #### stationInfo section
 255
 256 The syntax is similar to charging station configuration template with some added fields like the charging station id (name) and the 'Configuration' section removed.
 257
 258 #### configurationKey section
 259
 260 The syntax is similar to the charging station configuration template 'Configuration' section.
 261
 262 ## Docker
 263
 264 In the [docker](./docker) folder:
 265
 266 ```bash
 267 make
 268 ```
 269
 270 Or with the optional git submodules:
 271
 272 ```bash
 273 make SUBMODULES_INIT=true
 274 ```
