007ee642
JB		 33## Installation
34
35In the repository root, run the following command:
36
37```shell
38npm install
39```
40
41## Initial configuration
42
db70b600
JB		 43Copy the configuration template file [src/assets/config-template.json](src/assets/config-template.json) to [src/assets/config.json](src/assets/config.json).
44Copy 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
46Tweak them to your needs by following the section [configuration files syntax](README.md#configuration-files-syntax).
007ee642
JB		 47
48## Start
49
50To start the program, run: `npm start`.
51
b5bd5435 52To start the program with a UI controller, run: `npm run start:server`.
007ee642
JB		 53Then, 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
4d3821a2 55## Configuration files syntax
2c28fc83 56
e7aeea18 57All configuration files are in the JSON standard format.
2c28fc83 58
ff82dc5f 59**Configuration files locations**:
2c28fc83 60
170bec53 61- charging stations simulator configuration: [src/assets/config.json](src/assets/config.json);
1816f743 62- charging station configuration templates: [src/assets/station-templates](src/assets/station-templates);
1c51fd1d 63- charging station configurations: [dist/assets/configurations](dist/assets/configurations);
7f818162 64- charging station RFID tags lists: [src/assets](src/assets).
2c28fc83 65
1816f743
JB		 66The 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
68All charging station configuration templates are in the directory [src/assets/station-templates](src/assets/station-templates).
69
70A 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
1c51fd1d 741. charging station configuration: [dist/assets/configurations](dist/assets/configurations);
1816f743 752. charging station configuration template: [src/assets/station-templates](src/assets/station-templates);
170bec53 763. charging stations simulator configuration: [src/assets/config.json](src/assets/config.json).
511780c3 77
e7aeea18 78The charging stations simulator have an automatic configuration files reload feature at change for:
511780c3 79
170bec53 80- charging stations simulator configuration;
1816f743 81- charging station configuration templates;
170bec53 82- charging station authorization RFID tags lists.
2c28fc83 83
c645fe94 84But 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.

1816f743 249
a9ec2018 250The charging station configuration file is automatically generated at startup from the charging station configuration template file and is persistent.
1816f743
JB		 251
252The 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
256The 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
260The syntax is similar to the charging station configuration template 'Configuration' section.
