tags???

[h0leee]

In the video, I didn't understand what this line of code does ad I didn't understand wen i researched it either... Can somebody explain please?

module.exports.tags = ["all", "mocks"]

hardhat-deploy executes all deploy scripts by default. Tags allow you to easily execute one or a subset of deploy scripts.

Say you have many contracts but only want to deploy your mocks. All you have to do is write npx hardhat deploy --tags mocks

ohhhhh thanks!! And why put it in module.exports??

[Koowah]

If you look at your deploy script, you'll notice it is exported as a module with :

module.exports = async ...

By writing module.exports.tags = ["all", "mocks"], you're just saying that you want to add these tags attributes to the current (deploy) module. Makes sense ?

ok, but to do that dont i need to import the tags to the file?
