1D curve stitching / merging

Create a .env file

Copy env.base to .env and modify it according to your needs.

Start file provider mocking server

Note that the mocking server needs Python Flask.

First check if flask is installed:

python -c "import flask; print(flask.__version__);"

If no errors are displayed, you are good to go. Otherwise install Flask:

pip install Flask --user

To launch the server:

cd src/assets
python server.py

Or in a different host / port:

usage: server.py [-h] [--host [HOST]] [--port [PORT]]

optional arguments:
  -h, --help            show this help message and exit
  --host [HOST], -o [HOST]
                        default host: localhost
  --port [PORT], -p [PORT]
                        default port: 8000

The server can be tested with: http://localhost:8000/files/sans1d/A1_m_Iq_wedge_0.txt

Build Setup

Install dependencies

npm install

Serve with hot reload

By default the node server is launched on localhost:8080.

npm run dev

See .env the variables for other configurations:

NODE_HOST = ...
NODE_PORT = ...

Build for production with minification

Note:

This is not working yet.

npm run build
