## Start SQL
mysqld_safe&
sleep 5
## http server:
nginx
## Set up some files:
cd /mempool.space/backend
rm -f cache.json
touch cache.json
## Build mempool-config.json file ourseleves.
## We used to use jq for this but that produced output which caused bugs,
## specifically numbers were surrounded by quotes, which breaks things.
## Old command was jq -n env > mempool-config.json
## This way is more complex, but more compatible with the backend functions.
## Define a function to allow us to easily get indexes of the = string in from the env output:
strindex() {
x="${1%%$2*}"
[[ "$x" = "$1" ]] && echo -1 || echo "${#x}"
}
## Regex to check if we have a number or not:
NumberRegEx='^[0-9]+$'
## Delete the old file, and start a new one:
rm -f mempool-config.json
echo "{" >> mempool-config.json
## For each env we add into the mempool-config.json file in one of two ways.
## Either:
## "Variable": "Value",
## if a string, or
## "Variable": Value,
## if a integer
for e in `env`; do
if [[ ${e:`strindex "$e" "="`+1} =~ $NumberRegEx ]] ; then
## Integer add:
echo "\""${e:0:`strindex "$e" "="`}"\": "${e:`strindex "$e" "="`+1}"," >> mempool-config.json
else
## String add:
echo "\""${e:0:`strindex "$e" "="`}"\": \""${e:`strindex "$e" "="`+1}$"\"," >> mempool-config.json
fi
done
## Take out the trailing , from the last entry.
## This means replacing the file with one that is missing the last character
echo `sed '$ s/.$//' mempool-config.json` > mempool-config.json
## And finally finish off:
echo "}" >> mempool-config.json
## Start mempoolspace:
node dist/index.js

# Mempool Space
This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 8.1.2.
## Development server
Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
## Code scaffolding
Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
## Build
Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `--prod` flag for a production build.
## Running unit tests
Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
## Running end-to-end tests
Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
## Further help
To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md).
