Installation

These packages require authentication to install from GitHub Packages. First, create a .npmrc file:

# Create .npmrc file in your project root
echo "@cowprotocol:registry=https://npm.pkg.github.com" > .npmrc
echo "//npm.pkg.github.com/:_authToken=YOUR_GITHUB_TOKEN" >> .npmrc

To get your GitHub token:

1. Go to https://github.com/settings/tokens
2. Click "Generate new token (classic)"
3. Check only the "read:packages" scope
4. Copy the token and replace YOUR_GITHUB_TOKEN in the .npmrc file

Then install any of the packages above, either by exact version (i.e. @cowprotocol/[email protected]) or more conveniently by using the tag (@cowprotocol/cow-sdk@pr-660):

# Yarn
yarn add npm:@cowprotocol/cow-sdk@pr-660

# pnpm
pnpm install npm:@cowprotocol/cow-sdk@pr-660

# NPM
npm install npm:@cowprotocol/cow-sdk@pr-660

Update to the latest version (only if you used the tag)

Every commit will publish a new package. To upgrade to the latest version, run:

# Yarn
yarn upgrade @cowprotocol/cow-sdk

# pnpm
pnpm update @cowprotocol/cow-sdk

# NPM
npm update @cowprotocol/cow-sdk
