# Build Support Stack

## Instructions

JS/TS/NPM builds need an npm registry to store intermediate package artifacts.
This can be supplied by the user (e.g. using a hosted registry or even npmjs.com), or a local registry using gitea can be deployed by stack orchestrator.
To use a user-supplied registry set these environment variables:

`CERC_NPM_REGISTRY_URL` and 
`CERC_NPM_AUTH_TOKEN`

Leave `CERC_NPM_REGISTRY_URL` un-set to use the local gitea registry.

### 1. Build support containers
```
$ laconic-so --stack build-support build-containers
```
Note that the scheme/gerbil builder container can take a while to build so if you aren't going to build scheme projects it can be skipped with:
```
$ laconic-so --stack build-support build-containers --exclude cerc/builder-gerbil
```
### 2. Deploy Gitea Package Registry

```
$ laconic-so --stack package-registry setup-repositories
$ laconic-so --stack package-registry deploy up
This is your gitea access token: 84fe66a73698bf11edbdccd0a338236b7d1d5c45. Keep it safe and secure, it can not be fetched again from gitea.
```
Now npm packages can be built:
### Build npm Packages
Ensure that `CERC_NPM_AUTH_TOKEN` is set with the token printed above when the package-registry stack was deployed (the actual token value will be different than shown in this example):
```
$ export CERC_NPM_AUTH_TOKEN=84fe66a73698bf11edbdccd0a338236b7d1d5c45
$ laconic-so build-npms --include laconic-sdk
```
