How to install packages
Requirements
1. Install CLI tool
npm i -g ic-mops
This command will install cli tool
mops
2. Configure dfx.json
Add
mops
as a packtool to your dfx.json
... "defaults": { "build": { "packtool": "mops sources" } }, ...
3. Initialize
Run this command in the root directory of your project (where is
dfx.json
placed)If there are Vessel config files, mops will migrate packages from
vessel.dhall
to mops.toml
mops init
4. Install Motoko Packages
Use
mops add <package_name>
to install a specific package and save it to mops.toml
mops add base
You can also add packages from GitHub like this
mops add https://github.com/dfinity/motoko-base
For GitHub-packages you can specify branch, tag, or commit hash by adding
#<branch/tag/hash>
mops add https://github.com/dfinity/motoko-base#moc-0.9.1
You can also add local packages like this (put source files inside
src
directory)mops add ./shared
Use
mops install
to install all packages specified in mops.toml
mops install
5. Import Package
Now you can import installed packages in your Motoko code
import PackageName "mo:<package_name>";
for example
import Itertools "mo:itertools/Iter";
