JavaScript based request builder for the Stable Diffusion API
npm install stable-diffusion-api-request-buildernpm i stable-diffusion-api-request-builder
javascript
const StableDiffusionRequestBuilder = require('../StableDiffusionRequestBuilder');
const request = new StableDiffusionRequestBuilder()
.setPrompt('A red apple on a table')
.setNegativePrompt('cgi, illustration')
.setSeed(1234);
console.log(request);
`
`javascript
{
"prompt": "A red apple on a table",
"negative_prompt": "cgi, illustration",
"seed": "1234"
}
`
Building a conditional request
`javascript
const StableDiffusionRequestBuilder = require('../StableDiffusionRequestBuilder');
const buildRequest = (prompt, seed) => {
const request = new StableDiffusionRequestBuilder()
.setPrompt(prompt);
if (seed !== null) {
request.setSeed(seed);
}
return request;
};
console.log(buildRequest("A red apple on a table", 1234));
console.log(buildRequest("A red apple on a table", null));
`
`javascript
{
"prompt": "A red apple on a table",
"seed": 1234
}
{
"prompt": "A red apple on a table",
"seed": -1
}
`
Applying a saved template
Apply a saved template to the request builder to add onto.
`javascript
const template = {
seed: 1234,
prompt: 'A red apple on a table',
sampler_index: 'DPM++ 2M Karras',
enable_hr: true
};
const request = new StableDiffusionRequestBuilder()
.applyTemplate(template);
console.log(request);
`
`javascript
{
seed: 1234,
prompt: 'A red apple on a table',
sampler_index: 'DPM++ 2M Karras',
enable_hr: true
}
`
The builder will filter out parameters that are not valid for the request.
`javascript
const template = {
seed: 1234,
prompt: 'A red apple on a table',
sampler_index: 'DPM++ 2M Karras',
enable_hr: true,
invalid_parameter: 'bad parameter'
};
const request = new StableDiffusionRequestBuilder()
.applyTemplate(template);
console.log(request);
`
`javascript
{
seed: 1234,
prompt: 'A red apple on a table',
sampler_index: 'DPM++ 2M Karras',
enable_hr: true
}
`
Defaults
Be default, the builder will return an empty text prompt and a seed of -1. This will cause Stable Diffusion to generate a random seed.
`javascript
const request = new StableDiffusionRequestBuilder();
console.log(request);
`
`javascript
{
prompt: "",
seed: -1
}
