Building

Prerequisites

This assumes you have a working go environment with a GOPATH env var setup, and nodejs and npm installed:

sudo apt install nodejs-legacy npm snapcraft bzr

Install global npm modules without sudo:

cat > ~/.npmrc <<-EOF
root = $HOME/node/lib/node_modules
prefix = $HOME/node
binroot = $HOME/node/bin
manroot = $HOME/node/man
EOF

Setup the environment:

mkdir ~/node
export PATH=$PATH:$HOME/node/bin:$GOPATH/bin
export NODE_PATH=$HOME/node/lib/node_modules

Branch:

mkdir -p $GOPATH/src/github.com/snapcore
cd $GOPATH/src/github.com/snapcore
git clone git@github.com:snapcore/snapweb.git
cd snapweb

Install:

# this script does a npm install using yarn and fixes some extra issues
# with dependencies
./scripts/npm-install.sh
./scripts/get-go-deps.sh

Building

cd $GOPATH/src/github.com/snapcore/snapweb
# omit the architecture specified below ('amd64') to build for all architectures at once
./build.sh amd64

Installing

Once you have a snap built locally, you can test it on your system by doing:

 snap install snapweb_<version>.snap --dangerous

The --dangerous flag is necessary for installing locally built snaps, which have not been signed by the store.

Using

Connect to the Snapweb interface with this URL: [http://localhost:4200/]

Snapweb will automatically redirect to HTTPS on port 4201, using a self-signed certificate.

Warning : if testing snapweb inside a VM with redirected ports, be sure to connect directly to the HTTPS socket, as the HTTP redirect won't work.

For example, starting a VM with:

 kvm -m 768 -redir :8022::22 -redir :8201::4201 -hda snappy.img

Point the browser directly to [https://localhost:8201]

Note that in all cases you will now need an access token to use snapweb. Depending on where you installed the snap package (locally or in a vm) run the following command (possibly via ssh in the case of a vm):

 sudo snapweb.generate-token

Then copy/paste the token in the Web UI when requested.

API

/api/v2/packages/

To install a package:

 curl -H "Content-Type: application/json" -d '{"package":"xkcd-webserver"}' http://localhost:4200/api/v2/packages/

To uninstall a package:

curl -X DELETE http://localhost:4200/api/v2/packages/xkcd-webserver

To list packages:

 curl http://localhost:4200/api/v2/packages/

To get a specific package:

 curl http://localhost:4200/api/v2/packages/xkcd-webserver

Dependencies handling

To generate dependencies.tsv you need godeps, so

go get launchpad.net/godeps

To obtain the correct dependencies for the project, run:

godeps -t -u dependencies.tsv

If the dependencies need updating

godeps -t ./... > dependencies.tsv
