53## Installation
54
55### Prerequisites
56
57Install the [node.js](https://nodejs.org/) current LTS or superior version runtime environment:
58
59#### Windows
60
61- [Chocolatey](https://chocolatey.org/):
62
63```powershell
64choco install -y nodejs
65```
66
67#### MacOSX
68
69- [Homebrew](https://brew.sh/):
70
71```shell
72brew install node
73```
74
75#### GNU/Linux
76
77- [NodeSource](https://github.com/nodesource/distributions) node.js binary distributions for all supported versions.
78
79### Development prerequisites (optional)
80
81Install [volta](https://volta.sh/) for managing automatically the node.js runtime and package manager version:
82
83#### Unix
84
85```shell
86curl https://get.volta.sh | bash
87```
88
89#### Windows
90
91```powershell
92choco install -y volta
93```
94
95Setup [volta](https://volta.sh/) with [pnpm](https://github.com/pnpm/pnpm) package manager support: https://docs.volta.sh/advanced/pnpm
96
97### Branching model
98
99The `main` branch is the default development branch.
100The `vX` branches are the maintenance branches for the corresponding major version `X`.
101The `vX.Y` branches are the maintenance branches for the corresponding major and minor version `X.Y`.
102
103### Dependencies
104
105Enable corepack, if [volta](https://volta.sh/) is not installed and configured, and install latest pnpm version:
106
107```shell
108corepack enable
109corepack prepare pnpm@latest --activate
110```
111
112In the repository root, run the following command:
113
114```shell
115pnpm install
116```
117
118## Initial configuration
119
120Copy the configuration template file [src/assets/config-template.json](./src/assets/config-template.json) to [src/assets/config.json](./src/assets/config.json).
121Copy the RFID tags template file [src/assets/idtags-template.json](./src/assets/idtags-template.json) to [src/assets/idtags.json](./src/assets/idtags.json).
122
123Tweak them to your needs by following the section [configuration files syntax](#configuration-files-syntax): OCPP server supervision URL(s), charging station templates, etc.
124
125## Start simulator
126
127```shell
128pnpm start
129```
130
131## Start Web UI
132
133See Web UI [README.md](./ui/web/README.md) for more information.
134
135## Configuration files syntax
136
137All configuration files are using the JSON standard syntax.
138
139**Configuration files locations**:
140
141- charging stations simulator configuration: [src/assets/config.json](./src/assets/config.json);
142- charging station configuration templates: [src/assets/station-templates](./src/assets/station-templates);
143- charging station configurations: [dist/assets/configurations](./dist/assets/configurations);
144- charging station RFID tags lists: [src/assets](./src/assets).
145
146The 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).
147
148All charging station configuration templates are in the directory [src/assets/station-templates](./src/assets/station-templates).
149
150A list of RFID tags must be defined for the automatic transaction generator in a file with the default location and name: `src/assets/idtags.json`. A template file is available at [src/assets/idtags-template.json](./src/assets/idtags-template.json).
151
152**Configuration files hierarchy and priority**:
153
1541. charging station configuration: [dist/assets/configurations](./dist/assets/configurations);
1552. charging station configuration template: [src/assets/station-templates](./src/assets/station-templates);
1563. charging stations simulator configuration: [src/assets/config.json](./src/assets/config.json).
157
158The charging stations simulator has an automatic configuration files reload feature at change for:
159
160- charging stations simulator configuration;
161- charging station configuration templates;
162- charging station authorization RFID tags lists.
163
164But the modifications to test have to be done to the files in the build target directory [dist/assets](./dist/assets). Once the modifications are done, they have to be reported to the matching files in the build source directory [src/assets](./src/assets) to ensure they will be taken into account at next build.

390
391The charging station configuration file is automatically generated at startup from the charging station configuration template file and is persistent.
392
393The 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.
394

399That section is overwritten on matching charging station configuration template file changes.
400
401#### connectorsStatus section
402
403The syntax is similar to charging station configuration template 'Connectors' section with some added fields.

572Client->>UI Server: request
573UI Server->>Client: response
574Note over UI Server,Client: HTTP or Websocket
575```
576
577### Websocket Protocol
578
579SRPC protocol over Websocket. PDU stands for 'Protocol Data Unit'.
580
581- Request:
582 [`uuid`, `ProcedureName`, `PDU`]
583 `uuid`: String uniquely representing this request
584 `ProcedureName`: The procedure to run on the simulator
585 `PDU`: The parameters for said procedure
586
587- Response:
588 [`uuid`, `PDU`]
589 `uuid`: String uniquely linking the response to the request
590 `PDU`: Response parameters to requested procedure
591
592To learn how to use the Websocket protocol to pilot the simulator, an [Insomnia](https://insomnia.rest/) Websocket requests collection is available in [src/assets/ui-protocol](./src/assets/ui-protocol) directory.
593
594#### Version 0.0.1
595
596Set the Websocket header _Sec-Websocket-Protocol_ to `ui0.0.1`.
