Install pnpm, then:
pnpm install
pnpm dev
Navigate to localhost:3000
The purpose of the manager app is to expose the functionality of the ENS protocol in a user friendly manor.
ENS is a decentralized naming system that runs on the ethereum blockchain. The main purpose of ENS is to convert unfriendly blockchain addresses into human readable names (e.g. 0xb8c2c29ee19d8307cb7255e1cd9cbde883a267d5 -> nick.eth), but ENS has grown into so much more than that. For more info please visit our docs site.
Web3 is the term used to describe the blockchain enabled web, web2 is the 'legacy' more centralized web. Much of this app is built in tech that will be familiar to many web2 devs.

You must have Docker installed to run the test environment. For more information on the environment, see ens-test-env.
Once installed, you can run:
pnpm denv
pnpm dev:glocal
You can now navigate to http://localhost:3000
to see the app running off of a
local blockchain.
You will need a browser wallet to develop and test blockchain interactions. Download the Metamask browser extension here.
During the setup flow choose "Import existing wallet".
When it asks for your "Secret recovery phrase", use
test test test test test test test test test test test junk
You can then follow the instructions here to connect metamask to our local dev blockchain.
You should now have 10,000 ETH (local network eth) in your wallet. You're a legend on your local machine.
Github action scripts can be found in .github/workflows
The App is hosted on cloudflare and IPFS
Much of the logic around interacting with the ENS contracts has been extraced into this library. This is mostly so that we can help to make the experience of interacting with ENS as simple as possible for other developers.
As we have many different applications, and also would like to support the community, we have developed a design system in order to ensure consistent styling across the board.
Pages folder has basic route layout and basic react needed for rendering pages. These files should be kept relatively simple
Components that pages consume are kept in the components folder. This folder has a structure that mimics the structure of the pages folder. If a component is only used on a specific page then it goes into the corresponding folder in the components folder.
If a component is used across multiple pages and other components,
then it goes into the atoms
and molecules
folder (link to atoms and molecules thingy).

Transaction store is responsible for keeping track of the state of transactions.
We noticed transactions always follow a similar pattern and so created an internal API to streamline this. A transaction flow is a series of steps that occur in a modal, culminating in a successful or failed transaction. Transactions can have either an intro or an input step before the transaction step.
- Switch to test account 1 (the second account).
- Go to 'My Names'
- Select
migrated-resolver-to-be-updated.eth
- Click send
- The Modal that pops up is rendered by the
TransactionDialogManager
, which is rendered byTransactionFlowProvider
. The logic for rendering the different steps is contained here. - This button is in
RolesSection.tsx
, which gets its actions fromuseRoleActions.tsx
. TheonClick
property here callsshowSendNameInput
fromusePreparedDataInput
. This is a helper function provided by theuseTransactionFlow
hook. We have various input components prepared already, they are defined insrc/transaction-flow/input
. This one is usinginput/SendName
. Once the form data has been submitted we dispatch two actions to theTransactionFlowProvider
reducer. One to set the transactions required, and the next one to advance to the next step of the transaction flow. - Enter any address or ENS name that exists in the dev environment
- You should see a summary of changes, indicating the steps/transactions required
- Follow the steps through and complete the multiple transactions
- The code for managing the sending of transactions is in
TransactionStageModal
.
This is for when the graph is behind and we are waiting for it to catchup.
TBC
ENS names are NFTs. NFTs can have metadata associated with them, that is data associated with them that is not stored directly on-chain. One of the main use cases of this is to display a nice image that represents the ENS name. You can see an example of this here.

pnpm test
pnpm test:watch
pnpm test:coverage
You shouldn't deploy the subgraph on top of the existing dataset, instead you should create a clean dataset (explained below).
- Start the test environment
pnpm denv --save
- Deploy the subgraph
After the deploy scripts have run, you can deploy the subgraph. Assuming you are in the ens-subgraph repo, you can use:
yarn setup
- Wait for the subgraph to sync
Similar to the update process, a good indicator of sync status is if you see this message:
no chain head update for 30 seconds, polling for update, component: BlockStream
Dissimilar to the update process however is that you will never need to mine blocks manually.
- Exit the test environment
You can exit out of the test environment using Ctrl C
.
Once exited, you can commit the data to your branch. You do not need to run a separate save command.
Our e2e tests are split into two categories, stateless and stateful. Stateless test use the development environment, are faster, and is the general recommended way to write integration tests. Occasionally, you may need to test a feature that requires an external API or service. In this case, you can use the stateful tests. These tests are slower,
Running the entire stateless test suite:
pnpm denv
pnpm dev:glocal
pnpm e2e
Running a single test within a browser:
pnpm denv
pnpm dev:glocal
pnpm e2e < filename >:< linenumber > --headed
Running the entire stateful test suite:
pnpm dev
pnpm e2e:stateful
Running a single stateful test within a browser:
pnpm dev
pnpm e2e:stateful < filename >:< linenumber > --headed
The most important function in the e2e stateless tests is makeName
. This function is used to create a unique name for each test. This is important because we want to avoid any conflicts between tests.
const name = await makeName({
label: 'name',
type: 'legacy',
owner: '0x1234567890123456789012345678901234567890',
manager: '0x1234567890123456789012345678901234567890',
resolver: '0x1234567890123456789012345678901234567890',
records: {
texts: [{
key: 'text',
value: 'value'
}],
coins: [{
coin: 'eth',
value: '0x1234567890123456789012345678901234567890'
}],
contentHash: 'bafybeico3uuyj3vphxpvbowchdwjlrlrh62awxscrnii7w7flu5z6fk77y',

}

})
A single or an array of names to create. Each name can have the following properties:
label: string
The label of the name.
type: legacy | legacy-register | wrapped*
The type of the name. legacy names adopt the original data structure of ENS and are not ERC1155 complaint. wrapped names are names that have been wrapped with the NameWrapper contract and are ERC1155 compliant. legacy-register names simulate how mass registration services register names, usually without a resolver of other options that may increase gas.
owner: user | user2 | user3
defaults to owner
The address of the owner of the name.
manager: user | user2 | user3
defaults to value of owner
The address of the manager of the name. Only applicable to legacy and legacy-registr names.
duration: number
defaults to 365 days in seconds
The number of seconds the name will be registered for. Negative values are allowed to simulate names that have expired or are in the grace period.
secret: hex
defaults to a zero hex
The secret used during the register process. You will most likely not need to set this value.
resolver: address
defaults to the legacy resolver for legacy names and the latest resolver for wrapped names
The address of the resolver for the name. Used to test cases where the resolver is misconfgured or not set.
addr: address
defaults to the address of the owner
The address record for the name. Is used to test cases where the eth address is not set.
records: RecordOptions
The records for the name. Below is a type definition for the records object.
type RecordOptions = {
texts: {
key: string,
value: string
}[]
coins: {
coin: string | number,
value: string
}[]
contentHash: string
abi: AbiObject
}
fuses: FusesType
applicable to wrapped names only
The fuses to burn for a wrapped name. Below is a type definition for the fuses object. Note that PARENT_CANNOT_CONTROL is not fuse option as it is burned by default when a 2LD name is wrapped.
type FusesType = {
named: Array<"CANNOT_UNWRAP" | "CANNOT_BURN_FUSES" | "CANNOT_TRANSFER" | "CANNOT_SET_RESOLVER" | "CANNOT_SET_TTL" | "CANNOT_CREATE_SUBDOMAIN" | "CANNOT_APPROVE">
}
subnames: SubnameType[]
The subnames for the name. Below is a type definition for the subname object.
type SubnameType = {
label: string
type: 'legacy' | 'wrapped'
resolver: string
records: RecordOptions
duration: number
subnames: SubnameType[]
fuses: FusesType // Only applicable to wrapped names
}
timeOffset: number
defaults to 0
The duration in seconds to move the blockchain forward after the name has been registered. In rare use cases, usually when you are testing a name with a negative duration, the blockchain may need to be moved forward after all the transactions before it will resolve correctly.
syncSubgraph: boolean
defaults to true
Whether to wait for the subgraph to sync before returning the name. It is useful to set this value to false when you are testing a feature that does not rely on the subgraph to speed up the tests.
Returns a string for the 2LD name that is made up of the label with a timestamp appended to it and .eth TLD. The appended timestamp ensures that each time that a name is generated that it is unique.

- Install yalc globally:
npm i -g yalc
- Run relevant update script within external repo, for example:
# Example publish script for ENSjs, be aware this may have changed.
pnpm publish:local:ensjs
- Run pnpm install within this repo:
pnpm install
If updating an existing yalc installation, you can add the --force
flag.
any
is strictly prohibited, tempting as it may be.- Prefer small functions that do one thing.
- Most business logic should be outside of hooks, e.g. useEffect, useQuery etc is just there to manage react rendering and should be small, most of the logic should be in pure functions
ts-pattern
for conditionally rendering components when something more than a ternary expression is needed- Critical pieces of logic should be unit tested
Our testing philosophy is user-centric, meaning we want to write out tests so that they resemble the way a user would use our app as much as possible. We've borrowed this from the excellent testing-library.
A user generally clicks, types and swipes, and so most tests should include one of these actions. A user may also load a page in a specific state (by clicking, typing or swiping outside of the app) so sometimes we just want to check a page renders correctly. The vast majority of our tests will be of these kinds.
For deeper parts of the codebase that aren't directly related to a user interaction, such as utility functions, the user is the developer. So simply test the code in the way a developer would use it.
Install Knip as a development dependency in your project:
pnpm add -D knip
Add a script to your package.json for easy access to Knip:
{
"scripts": {
...,
"knip": "knip",
"knip:fix": "knip --fix --allow-remove-files"
}
}
Create a knip.config.ts
file at the root of your project. For more detail of configuration options, refer to the knip.config.ts file in the ENSDomains repository.
To analyze your project, run Knip using the following command:
pnpm knip
Knip will exit with code 1
if any issues are found, such as unused files, dependencies, or exports that need to be removed.
After Knip completes its analysis, review the results. Manually remove any unused files that are safe to delete, or let Knip handle it automatically with the following command:
pnpm knip:fix
Ensure you carefully examine any files marked for removal to avoid accidentally deleting necessary code.
After removing files, it's important to run your unit and end-to-end tests to ensure that everything is still functioning correctly:
pnpm test:coverage
pnpm e2e
