Fast apps are required on the internet at the age of information.
There are multiple techniques and strategies to build fast apps, one of them is getting the app JavaScript bundles to users’ browsers as quickly as possible. In Angular 8/9, there are many ways to do that!
You can instruct Angular to preload your bundles. You can even specify which of your bundles you want preload.
You can either use a built-in or making a custom preload strategy.
In this post, we’ll see by example how to preload your Angular 8/9 bundles.
By default, Angular doesn’t preload any bundles. But you can easily change that using the built-in preload strategy PreloadAllModules.
Provided that you have configured the router in your project in the src/app/app-routing.module.ts file, simply update is as follows:
import { RouterModule, Routes, PreloadAllModules } from '@angular/router';
@NgModule({
imports: [
RouterModule.forRoot(routes, { preloadingStrategy: PreloadAllModules })
],
exports: [RouterModule]
})
export class AppRoutingModule {}
We simply need to provide an options object with the preloadingStrategy
to the forRoot()
function.
If you are not satisfied with the built-in preload strategy you can create a custom Angular preloading strategy.
If you need to increase the performance of your Angular application use route-level code-splitting:
First, choose the right preloading strategy depending on the size of your application:
PreloadAllModules
strategy.Next, you need to configure the preloading strategy by setting the preloadStrategy
property of the Angular router.

A new Cumulus-based Substrate node, ready for hacking :cloud:
This project is a fork of the Substrate Node Template modified to include dependencies required for registering this node as a parathread or parachain to an established relay chain.
👉 Learn more about parachains here, and parathreads here.
Follow these steps to prepare a local Substrate development environment :hammer_and_wrench:
If necessary, refer to the setup instructions at the Substrate Developer Hub.
Once the development environment is set up, build the Cumulus Parachain Template. This command will build the Wasm Runtime and native code:
cargo build --release
NOTE: In the following two sections, we document how to manually start a few relay chain nodes, start a parachain node (collator), and register the parachain with the relay chain.
We also have the
polkadot-launch
CLI tool that automate the following steps and help you easily launch relay chains and parachains. However it is still good to go through the following procedures once to understand the mechanism for running and registering a parachain.
To operate a parathread or parachain, you must connect to a relay chain. Typically you would test on a local Rococo development network, then move to the testnet, and finally launch on the mainnet. Keep in mind you need to configure the specific relay chain you will connect to in your collator chain_spec.rs
. In the following examples, we will use rococo-local
as the relay network.
Clone and build Polkadot (beware of the version tag we used):
# Get a fresh clone, or `cd` to where you have polkadot already:
git clone -b v0.9.7 --depth 1 https://github.com/paritytech/polkadot.git
cd polkadot
cargo build --release
First, we create the chain specification file (chainspec). Note the chainspec file must be generated on a single node and then shared among all nodes!
👉 Learn more about chain specification here.
./target/release/polkadot build-spec \
--chain rococo-local \
--raw \
--disable-default-bootnode \
> rococo_local.json
We need n + 1 full validator nodes running on a relay chain to accept n parachain / parathread connections. Here we will start two relay chain nodes so we can have one parachain node connecting in later.
From the Polkadot working directory:
# Start Relay `Alice` node
./target/release/polkadot \
--chain ./rococo_local.json \
-d /tmp/relay/alice \
--validator \
--alice \
--port 50555
Open a new terminal, same directory:
# Start Relay `Bob` node
./target/release/polkadot \
--chain ./rococo_local.json \
-d /tmp/relay/bob \
--validator \
--bob \
--port 50556
Add more nodes as needed, with non-conflicting ports, DB directories, and validator keys (--charlie
, --dave
, etc.).
To connect to a relay chain, you must first _reserve a ParaId
for your parathread that will become a parachain. To do this, you will need sufficient amount of currency on the network account to reserve the ID.
In this example, we will use Charlie
development account where we have funds available. Once you submit this extrinsic successfully, you can start your collators.
The easiest way to reserve your ParaId
is via Polkadot Apps UI under the Parachains
-> Parathreads
tab and use the + ParaID
button.
To operate your parachain, you need to specify the correct relay chain you will connect to in your collator chain_spec.rs
. Specifically you pass the command for the network you need in the Extensions
of your ChainSpec::from_genesis()
in the code.
Extensions {
relay_chain: "rococo-local".into(), // You MUST set this to the correct network!
para_id: id.into(),
},
You can choose from any pre-set runtime chainspec in the Polkadot repo, by referring to the
cli/src/command.rs
andnode/service/src/chain_spec.rs
files or generate your own and use that. See the Cumulus Workshop for how.
In the following examples, we will use the rococo-local
relay network we setup in the last section.
We first generate the genesis state and genesis wasm needed for the parachain registration.
# Build the parachain node (from it's top level dir)
cd substrate-parachain-template
cargo build --release
# Folder to store resource files needed for parachain registration
mkdir -p resources
# Build the chainspec
./target/release/parachain-collator build-spec \
--disable-default-bootnode > ./resources/template-local-plain.json
# Build the raw chainspec file
./target/release/parachain-collator build-spec \
--chain=./resources/template-local-plain.json \
--raw --disable-default-bootnode > ./resources/template-local-raw.json
# Export genesis state to `./resources`, using 2000 as the ParaId
./target/release/parachain-collator export-genesis-state --parachain-id 2000 > ./resources/para-2000-genesis
# Export the genesis wasm
./target/release/parachain-collator export-genesis-wasm > ./resources/para-2000-wasm
NOTE: we have set the
para_ID
to be 2000 here. This must be unique for all parathreads/chains on the relay chain you register with. You must reserve this first on the relay chain for the testnet or mainnet.
From the parachain template working directory:
# NOTE: this command assumes the chain spec is in a directory named `polkadot`
# that is at the same level of the template working directory. Change as needed.
#
# It also assumes a ParaId of 2000. Change as needed.
./target/release/parachain-collator \
-d /tmp/parachain/alice \
--collator \
--alice \
--force-authoring \
--ws-port 9945 \
--parachain-id 2000 \
-- \
--execution wasm \

You see messages are from both a relaychain node and a parachain node. This is because a relay chain light client is also run next to the parachain collator.
Now that you have two relay chain nodes, and a parachain node accompanied with a relay chain light client running, the next step is to register the parachain in the relay chain with the following steps (for detail, refer to the Substrate Cumulus Worship):
Developer
-> sudo
page.paraSudoWrapper
-> sudoScheduleParaInitialize(id, genesis)
as the extrinsic type, shown below.id: ParaId
to 2,000 (or whatever ParaId you used above), and set the parachain: Bool
option to Yes.genesisHead
, drag the genesis state file exported above, para-2000-genesis
, in.validationCode
, drag the genesis wasm file exported above, para-2000-wasm
, in.Note: When registering to the public Rococo testnet, ensure you set a unique
paraId
larger than 1,000. Values below 1,000 are reserved exclusively for system parachains.
The collator node may need to be restarted to get it functioning as expected. After a new epoch starts on the relay chain, your parachain will come online. Once this happens, you should see the collator start reporting parachain blocks:
# Notice the relay epoch change! Only then do we start parachain collating!

Note the delay here! It may take some time for your relay chain to enter a new epoch.
Is this Cumulus Parachain Template Rococo & Westend testnets compatible? Yes!
See the Cumulus Workshop for the latest instructions to register a parathread/parachain on a relay chain.
NOTE: When running the relay chain and parachain, you must use the same tagged version of Polkadot and Cumulus so the collator would register successfully to the relay chain. You should test locally registering your parachain successfully before attempting to connect to any running relay chain network!
Find chainspec
files to connect to live networks here. You want to be sure to use the correct git release tag in these files, as they change from time to time and must match the live network!
These networks are under constant development - so please follow the progress and update of your parachains in lock step with the testnet changes if you wish to connect to the network. Do join the Parachain Technical matrix chat room to ask questions and connect with the parachain building teams.
