Welcome to Collection Generator CLI, this repository lets you generate, upload and mint NFT collection on Archethic Public Blockchain.
npm install -g @archethicjs/collection-generator-cliTo check if project is installed successfully, run the following command -
node index.js aboutFirst, create a config.json file with this structure (for example at the root of your project):
{
"namePrefix": "Your Collection",
"description": "Remember to replace this description",
"baseUri": "",
"supply": 500000000,
"name": "AE Collection",
"symbol": "AE05",
"layerConfigurations": [
{
"growEditionSizeTo": 5,
"layersOrder": [
{ "name": "Background" },
{ "name": "Eyeball" },
{ "name": "Eye color" },
{ "name": "Iris" },
{ "name": "Shine" },
{ "name": "Bottom lid" },
{ "name": "Top lid" },
]
}
],
"shuffleLayerConfigurations": false,
"debugLogs": false,
"format": {
"width": 512,
"height": 512,
"smoothing": false
},
"text": {
"only": false,
"color": "#ffffff",
"size": 20,

"yGap": 40,

},
"pixelFormat": {
"ratio": 0.015625
},
"background": {
"generate": true,
"brightness": "80%",
"static": false,
"default": "#000000"
},
"extraMetadata": {},
"rarityDelimiter": "#",
"uniqueDnaTolerance": 10000,
"addDnaToMetadata": false,
"addEditionToMetadata": false
}Create your different layers as folders in a 'layers' directory (this directory must be in the root), and add all the layer assets in these directories. You can name the assets anything as long as it has a rarity weight attached in the file name like so: example element#70.png. You can optionally change the delimiter # to anything you would like to use in the variable rarityDelimiter in the config.json file.
Once you have all your layers, go into your config.json and update the layerConfigurations objects layersOrder array to be your layer folders name in order of the back layer to the front layer.
Example: If you were creating a portrait design, you might have a background, then a head, a mouth, eyes, eyewear, and then headwear, so your layersOrder would look something like this:
"layerConfigurations": [
{
"growEditionSizeTo": 100,
"layersOrder": [
{ "name": "Head" },
{ "name": "Mouth" },
{ "name": "Eyes" },
{ "name": "Eyeswear" },
{ "name": "Headwear" },
]
}
],The name of each layer object represents the name of the folder (in /layers/) that the images reside in.
Optionally you can now add multiple different layerConfigurations to your collection. Each configuration can be unique and have different layer orders, use the same layers or introduce new ones. This gives the artist flexibility when it comes to fine tuning their collections to their needs.
Example: If you were creating a portrait design, you might have a background, then a head, a mouth, eyes, eyewear, and then headwear and you want to create a new race or just simple re-order the layers or even introduce new layers, then you're layerConfigurations and layersOrder would look something like this:
"layerConfigurations": [
{
// Creates up to 50 artworks
"growEditionSizeTo": 50,
"layersOrder": [
{ "name": "Background" },
{ "name": "Head" },
{ "name": "Mouth" },
{ "name": "Eyes" },
{ "name": "Eyeswear" },
{ "name": "Headwear" },
]
},
{
// Creates an additional 100 artworks
"growEditionSizeTo": 150,
"layersOrder": [
{ "name": "Background" },
{ "name": "Head" },
{ "name": "Mouth" },
{ "name": "Eyes" },
{ "name": "Eyeswear" },
{ "name": "Headwear" },
]
}
]Update your format size, ie the outputted image size, and the growEditionSizeTo on each layerConfigurations object, which is the amount of variation outputted.
You can mix up the layerConfigurations order on how the images are saved by setting the variable shuffleLayerConfigurations in the config.js file to true. It is false by default and will save all images in numerical order.
If you want to have logs to debug and see what is happening when you generate images you can set the variable debugLogs in the config.json file to true. It is false by default, so you will only see general logs.
When you are ready, run the following command and your outputted art will be in the build/images directory and the json in the build/json directory:
node index.js generate --config ./config.jsonconfig is the path of your config.json file.layers is the path to your NFT layers folder (optional, default to: ./layers)output is the path of your NFT collection building output (optional, default to: ./build)The program will output all the images in the build/images directory along with the metadata files in the build/json directory. Each collection will have a _metadata.json file that consists of all the metadata in the collection inside the build/json directory. The build/json folder also will contain all the single json files that represent each image file. The single json file of a image will look something like this:
{
"name": "Your Collection #1",
"description": "Remember to replace this description",
"image": "http://localhost:4000/api/web_hosting/0000c11d9aba1cf7228230c479e3c85f370065b0a7dddc99035e635de78faff263cb/1.png",

{
"trait_type": "Eyeball",

{
"trait_type": "Eye color",

"value": "Shapes"
},
{
"trait_type": "Bottom lid",
"value": "Low"
},
{
"trait_type": "Top lid",
"value": "Middle"
}
]
}You can also add extra metadata to each metadata file by adding your extra items, (key: value) pairs to the extraMetadata object variable in the config.js file.
const extraMetadata = {
creator: "Manuj Varma",
};If you don't need extra metadata, simply leave the object empty. It is empty by default.
const extraMetadata = {};That's it, you're done.
