[](https://www.npmjs.com/package/waifu-generator) [](https://snyk.io/test/github/TheRealBarenziah/waifu-generator?targetFile=package.json) # Usecase ? You need to generate random pngs for testing purposes, but [js-image-generator](https://www.npmjs.com/package/js-image-generator) is definitely too efficient and boring for the job? Look no further! TheRealBarenziah(tm) brings you this StyleGAN2-empowered[*](#BTW),industrial grade, uwu-compliant, yet unlicensed module! # Compatibility **node >= 8** (we're using [promises](https://node.green/)) # Use ```bash npm i --save-dev waifu-generator ``` **tl;dr** - `options` object is facultative - `options.filename` default to null - `options.path` default to null - `options.skipFs` default to false; pass `true` to skip the fs.createWriteStream() call - `options.withoutPrefix` default to false; pass `true` to remove 'data:image/png;base64,' prefix from returned string - `options.mosaic` default to null; **enable to create a mosaic of waifus.** [Infos here](#Mosaic) - `options.macrophilia` default to null; **enable to quickly create big files.** [Infos here](#Macrophilia) ## The Long Read ### Case 1 : default (no option object) In your `generate.js` file : ```javascript const generateWaifu = require("waifu-generator"); generateWaifu() .then(res => console.log(res)) .catch(e => console.error(e)); ``` Back in terminal (for the example): ```bash node ./generate.js # ...will write a random image file in cwd (current working directory). # The filename will follow the pattern "$imageId_$uuid.png" data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVQYV2NgYAAAAAMAAWgmWQ0AAAAASUVORK5CYII= # Since we logged the return value with .then(res => console.log(res)) # a base64 string representation of our image is printed in stdout. # It is facultative, but may come in handy. You can check the string by copypasting it # into your favorite browser, or whatever. Just know it's there, in the resolve value ! ``` ### Case 2 : providing an option object In your `generate.js` file : ```javascript const generateWaifu = require("waifu-generator"); const options = { filename: "sugoi_kawaii", path: "./__TESTS__/images" }; generateWaifu(options); ``` Back in terminal: ```bash node ./generate.js # ...will write a random image file in "./__TESTS__/images", # with "sugoi_kawaii.png" as its filename. # # No output since we didn't explicitely '.then(res => console.log(res));' ``` ### Case 2.5: skip the fs call Sometimes, you don't want your tests to do I/O operations (typically when you're after performance). In that case you can skip the filesystem call entierely, leaving you to work with pure base64 strings: ```javascript const generateWaifu = require("waifu-generator"); const yourCustomFunc = async () => { const base64waifu = await generateWaifu({ skipFs: true }); const output = base64waifu.toString().toString().toString(); // Example of arbitrary filth you're free to inflict to your base64 waifu here console.log(output); // printing our stuff return output; }; yourCustomFunc(); ``` **NB: Activating `skipFs` will indeed make the path/filename options irrelevant !** # Mosaic Available from 2.0.0 onward. Incompatible with `macrophilia`. Opt-in by defining `option.mosaic`: ```javascript const waifuGenerator = require("./index") waifuGenerator({ filename: "mosaic", // indeed compatible with other waifu-generator options mosaic: { number: 3, // mandatory; must be integer in 1-99 range options: { /* facultative merge-img option object one usecase is to generate near-infinite different (from a shasum perspective) files */ direction: true, color: 0x000000 } } }) ```
What do you mean by "thiqq"?
