Extracted subgraph configs (mainly contract addresses and `startBlock`
values) to a separate `subgraph-config.json` file. Now the actual
`subgraph.yaml` is generated in `build.sh` by filling the config options
to a Handlebars template.
We don't need separate environment specific `subgraph_* yaml` files
anymore.
## Implementation
There is a small `fill-handlebars-template.mjs` script which reads the
config from `stdin` and outputs the filled template to `stdout`. There
is no custom logic in that script, and alternative we could use some
ready-made external Handlebars utility instead of this script.
## Config file
The config file was generated from the existing `subgraph_*.yaml` files
by this script:
```js
import { readFileSync } from 'fs'
import yaml from 'js-yaml'
const ENVIRONMENT_IDS = ['dev2', 'polygon', 'polygonAmoy', 'peaq', 'iotex']
const output = {}
for (const environmentId of ENVIRONMENT_IDS) {
const fileId = (environmentId === 'polygonAmoy') ? 'amoy' : environmentId
const fileName = `subgraph_${fileId}.yaml`
const fileContents = readFileSync(fileName, 'utf8')
const yamlData = yaml.load(fileContents)
const contracts = {}
for (const dataSource of yamlData.dataSources) {
const source = dataSource.source
const key = (source.abi === 'NodeRegistry') ? 'StorageNodeRegistry' : source.abi
contracts[key] = {
address: source.address,
startBlock: source.startBlock
}
}
const networkId = (environmentId === 'polygon')
? 'matic' :
((environmentId === 'polygonAmoy') ? 'polygon-amoy' : environmentId)
output[environmentId] = {
networkId,
hubContracts: (environmentId !== 'iotex'),
contracts
}
}
console.log(JSON.stringify(output, undefined, 4))
```
## Small changes to subgraph.yaml output
The subgraph.yaml output generated by the `build.sh` matches almost
exactly the current files. Exceptions:
- removed some TODO comments
- unified quotes to be single quotes
- unified the description
See three commits in this PR for the exact unifications. There was also
test.sh script in commit
[bda37c6](bda37c6)
to check that the outputs match the current files.
## Notes about Iotex
Thet addresses in the `subgraph-config.json` matches the addresses which
were used in `subgraph_iotex.yaml`, but don't match the values of
`@streamr/config`. Therefore this PR doesn't change any functionality.
There is a separate PR about this
#1010 issue.
Also in that PR or in a follow-up PR we may add hub contracts to `iotex`
config. If we do that we should remove the `hubContracts` property from
the `subgraph-configs.json` (and the related if statement in
`subgraph.yaml.hbs`) as the value for that is true in environment.s

startBlocksto match contract creation blocks (the data is from iotexscan.io's contract pages: search by address, click transaction under "Contract creation", see value for "Block Height").
