if-plugin-template

if-plugin-template is an environmental impact calculator template which exposes an API for IF to retrieve energy and embodied carbon estimates.

Implementation

Here can be implementation details of the plugin. For example which API is used, transformations and etc.

Usage

To run the <YOUR-CUSTOM-PLUGIN>, an instance of PluginInterface must be created. Then, the plugin's execute() method can be called, passing required arguments to it.

This is how you could run the model in Typescript:

async function runPlugin() {
  const newModel = await new MyCustomPlugin().configure(params);
  const usage = await newModel.calculate([
    {
      timestamp: '2021-01-01T00:00:00Z',
      duration: '15s',
      'cpu-util': 34,
    },
    {
      timestamp: '2021-01-01T00:00:15Z',
      duration: '15s',
      'cpu-util': 12,
    },
  ]);

  console.log(usage);
}

runPlugin();

Testing model integration

Using local links

For using locally developed model in IF Framework please follow these steps:

1. On the root level of a locally developed model run npm link, which will create global package. It uses package.json file's name field as a package name. Additionally name can be checked by running npm ls -g --depth=0 --link=true.
2. Use the linked model in impl by specifying name, method, path in initialize models section.

name: plugin-demo-link
description: loads plugin
tags: null
initialize:
  plugins:
    my-custom-plugin:
      method: MyCustomPlugin
      path: "<name-field-from-package.json>"
      global-config:
        ...
...

Using directly from Github

You can simply push your model to the public Github repository and pass the path to it in your impl. For example, for a model saved in github.com/my-repo/my-model you can do the following:

npm install your model:

npm install -g https://github.com/my-repo/my-model

Then, in your impl, provide the path in the model instantiation. You also need to specify which class the model instantiates. In this case you are using the PluginInterface, so you can specify OutputModel.

name: plugin-demo-git
description: loads plugin
tags: null
initialize:
  plugins:
    my-custom-plugin:
      method: MyCustomPlugin
      path: https://github.com/my-repo/my-model
      global-config:
        ...
...

Now, when you run the manifest using the IF CLI, it will load the model automatically. Run using:

ie --manifest <path-to-your-impl> --output <path-to-save-output>
