Purchasing a Postage Stamp
Uploading a File
Creating an Identity
Uploading to a Feed
Description
Manage your Bee node and interact with the Swarm network via the CLI
The goal of this project is to handle most of the Swarm operations through CLI at some point in the future.
For the currently supported operations, see the Commands section.
Installation
Requires Node.js 18 or higher. It is recommended to use NVM to manage Node.js versions.
Warning! Installing Node.js via package managers (e.g.
apt
,yum
,brew
) may not work as expected, as they may install an older version of Node.js.
From npm
Install globally:
npm install --global @ethersphere/swarm-cli
From source
See the Development section.
Usage
The general usage is to provide a command, optionally a subcommand, then arguments and options.
swarm-cli command [subcommand] <arguments> [options]
Running a command with the --help
option prints out the usage of a command.

Example usage
Let's say we want to upload our website to Swarm and update a feed to point to the newest version. For updating a feed
we would need to sign it with an Ethereum key, so first we need to create one with the identity create
command:
swarm-cli identity create
This command will ask for a password. After that a new identity is created (named main
). Now we can use this identity
to sign updates. It's also possible to import and export Ethereum JSON V3 format identities that works with other apps
(e.g. wallets).
Another requirement for uploading to the Swarm network is a valid postage batch, also called a postage stamp or simply a
stamp. Stamps need to be purchased with xBZZ tokens. We can use the stamp buy
command to take care of this step. The
--amount
and --depth
options alter the capacity of the postage stamp. For example, running
stamp buy --amount 1 --depth 20
will get back with a Stamp ID after a while. We will be using that with the --stamp
option in commands which upload files, or write feeds.
For uploading to a feed we can use the feed upload
command. It expects the path of the folder (or file) we want to
upload and as options it expects identity
to be provided along with the password
that belongs to it, as well as the
earlier mentioned stamp
.
swarm-cli feed upload path-to-be-uploaded --identity my-identity --password my-secret-password --stamp stamp-id
In this example we are uploading the content of the dist
folder. If the uploading was successful the last printed line
will contain a Feed Manifest URL
. This URL can be opened in the browser. If the uploaded folder contains an
index.html
file then it will be automatically displayed when visiting the URL.
This URL will stay the same when we upload an updated version of the website. Because of this we can also put this URL
into a reverse proxy configuration or use the reference (the hex string after the /bzz/
) in an ENS record. There is
more information about that in the
Bee documentation. The uploaded content
can be found on the link in the line starting with URL
. This will change every time the content is modified.
Usability Features
Uploading Files, Folders, Websites, and Arbitrary Data from stdin
Files
Use swarm-cli
to upload a single file:
swarm-cli upload README.md
The command above will print a /bzz
URL that may be opened in the browser. If the browser is able to handle the file
format then the file is displayed, otherwise it will be offered to be downloaded.
Folders and Websites
swarm-cli
also supports uploading folders with the same upload
command:
swarm-cli upload build/
This also yields a /bzz
URL. If there is an index.html
present in the root of the folder, --index-document
will be
automatically applied by swarm-cli
. This option sets which file the browser should open for an empty path. You may
also freely set --index-document
during upload to change this.
Standard Input
You can pipe data from other commands to swarm-cli
using the --stdin
option.
curl -L https://picsum.photos/200 | swarm-cli --stdin --stamp [...]
Unlike other upload methods, this results in a /bytes
URL, which cannot be displayed by browsers normally. You can
still share your hash and others can download it. However, with the --name
option, you can give your arbitrary data a
file name, and swarm-cli
will attempt to determine the suitable content type for your data. Given it is successful,
swarm-cli
will print a /bzz
URL instead of the /bytes
URL, which is good to be displayed in browsers. Example:
curl -L https://picsum.photos/200 | swarm-cli --stdin --stamp [...] --name random.jpg
There is also a --content-type
option if you want to adjust it manually:
curl -L https://picsum.photos/200 | swarm-cli --stdin --stamp [...] --name random --content-type image/jpeg
Please note that stdin is reserved for the data you are uploading, so interactive features are disabled during this
time. Because of that, --stamp
must be passed beforehand. You may create an alias for grabbing the ID of the least
used postage stamp:
alias st='swarm-cli stamp list --least-used --limit 1 --hide-usage --quiet'
Leveraging the alias above, you can use a shortcut for uploading from stdin:
curl -L https://picsum.photos/200 | swarm-cli --stdin --stamp $(st)
Custom HTTP Headers
Similarly to curl
, you may use the --header
or -H
option to specify as many additional headers as you want, which
will be sent with all requests:
swarm-cli upload README.md -H "Authorization: [...]" -H "X-Custom-Header: Your Value"
Autocomplete
swarm-cli
has support for autocomplete in bash
, zsh
and fish
. This turns on <tab><tab>
suggestions which can
complete commands, paths and options for you.
To enable it, you need to install it once via two options:
- Running
swarm-cli --generate-completion
and following the instructions there - Running
swarm-cli --install-completion
which automatically appends the completion script to your configuration file
| Shell | Completion System | Configuration Path |
| ------ | ------------------------------------------------- | --------------------------------------- |
| bash
| compdef
& compadd
OR complete
& COMPREPLY
| $HOME/.bashrc
& $HOME/.bash_profile
|
| zsh
| compdef
& compadd
OR complete
& COMPREPLY
| $HOME/.zshrc
|
| fish
| complete
| $HOME/.config/fish/config.fish
|
Warning! If you start a subshell (e.g. running
bash
fromzsh
), yourSHELL
env variable would still be the old value! The generation and completion script cannot detect your shell accurately in that case, so please setSHELL
manually. It is generally advised to run--generate-completion
first to ensure the shell and the paths are properly detected.
Example:
$ SHELL=zsh
$ swarm-cli --generate-completion
Your shell is: zsh
Found configuration file path: /Users/Swarm/.zshrc
Append the completion script below to your configuration file to enable autocomplete.
You need to source your configuration, or restart your shell, to load the changes.
<script>
Numerical Separator and Units
As most of the units are specified in wei and PLUR - the smallest denominations of currencies - they are a bit difficult to write out.
To aid this, you may use underscores (_
) and K
, M
, B
and T
units to make your numbers more comprehensible.
Example:
swarm-cli stamp buy --amount 10M --depth 17 --gas-price 10_000_000_000_000
You may combine the two: 100_000T
.
Stamp Picker
Unless you are running in --quiet
mode, some options are not hard-required.
Look for hints in the --help
sections. Take the upload
command for example:
█ Required Options:
--stamp ID of the postage stamp to use [required when quiet][string]
That means, you don't have to provide the postage stamp ID beforehand. Simply running swarm-cli upload <path>
will
prompt you with an interactive stamp picker:
? Please select a stamp for this action.
Stamp ID Utilization
(Use arrow keys)
❯ b9d5bb548c2c209cb99cbb27b0bef59b8f0cd3558363e307f45177b5a64ad0c8 (1)
Identity Picker
Similarly to Stamp Picker, when an identity is not provided, an interactive picker will be prompted.
Take the command feed upload
for example. Albeit it takes quite a lot of options, you can run it with typing as little
as feed upload <path>
.
swarm-cli
will take you through some prompts to interactively specify all required options, such as identity
,
password
of the identity, and the mandatory stamp
.
Passing identities is also tolerant to errors, so if you provide one which does not exist, the output will tell you and you can correct it:
The provided identity does not exist. Please select one that exists.
? Please select an identity for this action (Use arrow keys)
❯ main
Human Readable Topics
You may need to pass topics on multiple occasions - for example, when uploading to feeds.
Topics are 32-byte long identifiers, so you need 64 characters to write them out in hexadecimal string format.
You can do that with the --topic
or -t
option, or alternatively take a shortcut and use a human readable string
which will be hashed by swarm-cli
for your convenience. It is available via the --topic-string
or -T
option.
Example:
swarm-cli feed upload [...] -T "Awesome Swarm Website"
This is also indicated in the --help
section:
-t --topic 32-byte long identifier in hexadecimal format [hex-string][default all zeroes]
-T --topic-string Construct the topic from human readable strings [string]
Only one is required: [topic] or [topic-string]
Manifest address scheme
The manifest
commands enable low-level operation on manifests. These always require a root manifest reference (hash)
argument as the input. Some commands, however, work with subparts of the manifest. A few examples are: downloading only
a folder from a manifest, listing files only under a specific path in a manifest, and adding files or folders not to the
root of the manifest, but under some path.
These can be achieved by using the bzz://<hash>/<path>
scheme in the <address>
argument as follows:
List entries under the /command/pss
prefix in manifest
1512546a3f4d0fea9f35fa1177486bdfe2bc2536917ad5012ee749604a7b425f
swarm-cli manifest list bzz://1512546a3f4d0fea9f35fa1177486bdfe2bc2536917ad5012ee749604a7b425f/command/pss
Download README.md
from manifest 1512546a3f4d0fea9f35fa1177486bdfe2bc2536917ad5012ee749604a7b425f
swarm-cli manifest download bzz://1512546a3f4d0fea9f35fa1177486bdfe2bc2536917ad5012ee749604a7b425f/README.md
Note: The
bzz://
protocol can be omitted.
Automating tasks with Swarm-CLI
Running swarm-cli
with the flag --quiet
(or -q
for short) disables all interactive features, and makes commands
print information in an easily parsable format. The exit code also indicates whether running the command was successful
or not. These may be useful for automating tasks both in CI environments and in your terminal too.
Below you will find a few snippets to give an idea how it can be used to compose tasks.
Connectivity
Exit if not all status checks succeed:
swarm-cli status -q || exit 1
Check Bee API connection, compatibility does not matter:
swarm-cli status -q | head -n 1 | grep "^OK"
Postage Stamps
Grab the first postage stamp:
swarm-cli stamp list --limit 1 --quiet --hide-usage
Grab the least used postage stamp:
swarm-cli stamp list --limit 1 --quiet --hide-usage --least-used
List all postage stamps with zero utilization:
swarm-cli stamp list --max-usage 0 --quiet --hide-usage
Sort postage stamps based on utilization (least utilized comes first):
swarm-cli stamp list --least-used --quiet
Uploading
Upload a file with the least utilized postage stamp (that has at most 50% usage):
STAMP=$(swarm-cli stamp list --max-usage 50 --least-used --limit 1 --quiet --hide-usage)
swarm-cli upload -q README.md --stamp $STAMP
Config
The configuration file is placed in a hidden folder named swarm-cli
.
In case of Unix-based systems this config path will be: $HOME/.swarm-cli
On Windows systems: $HOME\AppData\swarm-cli
The configuration file is saved with 600
file permission.
On first run, this configuration will be generated with default values, that you are able to change on your demand under the before mentioned path.
Assignment priority
It is possible to set value of particular parameters in different ways.
The assignment priority of how option gets its value in question is the following:
- passed CLI option value (with e.g.
--option-example-1
) - env variable for that option in form of either
OPTION_EXAMPLE_1
orSWARM_CLI_OPTION_EXAMPLE_1
(if it is available) - CLI configuration value of that option (if it is available)
- option's default fallback value (or it is required to define by #1)
System environment
With specific system environment variables you can alter the behaviour of the CLI
BEE_API_URL
- API URL of Bee clientSWARM_CLI_CONFIG_FOLDER
- full path to a configuration folderSWARM_CLI_CONFIG_FILE
- configuration file name, defaults to config.json
Development
After the project has been cloned, the dependencies must be installed. Run the following in the project folder:
$ npm install
Then you need to compile the TypeScript code:
$ npm run build
To make the local swarm-cli
files in the dist/
directory available as a global package:
$ npm link
If all went well you should be able to run swarm-cli
.
If npm link
fails, or you don't want to install anything, then you can use node dist/src/index.js
to run swarm-cli
from the checked out directory.
