Model converters and codegen for Concerto format model files.
npm install @accordproject/concerto-codegen --save
This API allows you to generate models of varying sizes (up to 100 MiB) which can be used to test the performance of your Concerto-handling code.
You can generate a model up to a specified number of declarations and properties using:
const benchmarkModelGenerator = new BenchmarkModelGenerator();
const generated = benchmarkModelGenerator.generateConcertoModels({
nDeclarations: 5, // Number of declarations in the model
nProperties: 5, // Number of properties per declaration
});You can generate a model up to a specified size in bytes, however you would need to specify how that model should grow.
If you'd like to grow it by number of declarations, you will need to specify the number of properties that you wish the model to have (defaults to 1):
const benchmarkModelGenerator = new BenchmarkModelGenerator();
const generated = benchmarkModelGenerator.generateConcertoModels({
generateUpToSize: 10000, // Target upper limit of growth in bytes
growBy: 'declarations', // Element type by which the model should grow
nProperties: 5, // Number of properties per declaration
});If you'd like to grow it by number of properties, you will need to specify the number of declarations that you wish the model to have (defaults to 1):
const benchmarkModelGenerator = new BenchmarkModelGenerator();
const generated = benchmarkModelGenerator.generateConcertoModels({
generateUpToSize: 10000, // Target upper limit of growth in bytes
growBy: 'properties', // Element type by which the model should grow
nProperties: 5, // Number of declarations in the model
});The expected response will include an array of generated models (currently containing only a single model) and a metadata object with information about the generated model e.g:
{
models: [
{
'$class': '[email protected]',
decorators: [],
namespace: '[email protected]',
imports: [],
declarations: [
...
]
}
],
metadata: {
requestedModelSizeInBytes: 10000,
humanReadableRequestedModelSize: '9.77 KiB',
generatedModelSizeInBytes: 9952,
humanReadableGeneratedModelSize: '9.72 KiB',
declarationsN: 5,
propertiesNInSmallestDeclaration: 15,
propertiesNInLargestDeclaration: 16
}
}As you can see from the above example model, the generator will try its best to reach the upper generateUpToSize requested size, but may fall short by a few bytes.
