MEAN stack programming with heroku

Node programming referring to https://www.heroku.com/home .


Partial modification of package.json

If you check the url created at heroku create, the web is created!




Next, try this one using mongo-db.
  • Using mlab, it is necessary to have a credit card registration on heroku. So refering this https://www.webprofessional.jp/building-facebook-chat-bot-node-heroku/ (in the middle of "How to set the database from mLab's site" or https://www.youtube.com/watch?v=cBfcbb07Tqk ), I linked Heroku to mlab.com.
  • Process.env.mongodb_uri appears in server.js, but this mongodb_uri seems to be already defined as an environment variable of heroku, so I registered this uri created by mlab to heroku.com.
  •  Drop the above sample application https://github.com/chrisckchang/mean-contactlist-angular2 (https://devcenter.heroku.com/articles/mean-apps-restful-api ) locally with git clone.
  • Remove the app.json because the above app assumes the mlab add-on. (App.json seems to be necessary when using heroku button) (2019.3.3 appending)
    There is no problem even if app.json remains.
  • Create an application with "heroku create".
  • After selecting the application created above on heroku.com, select "settings", "Reveal Config Vars", set the config Vars (environment variable) to MONGODB_URI and the value to mongodb: // ×× created in the sandbox at mlab.com.
    $heroku config: add environment variable = "XXX"
    is also ok.

  • Upload the application to heroku with $git push heroku master.
  • Completed when accessing url





After actually entering the data, if you look at the sandbox at mlab.com, the data you just entered is saved in json format.

On Friday afternoon, big earthquake had occured. I worked at office at Osaka. At first, next branch's team used TV conference to Tokyo office and tokyo team said earthquake had occured, and a few seconds later, we felt earthquake. Our office is at 11th floor and swing was very big so we felt very awful if our building was collapsed. It was about 2:30 PM. Afterthat, we switched our TV on and saw what happend in Japan, so our work had almost stopped afterthat. (safely, my house in Osaka and my parents and brother and sister's house in Shizuoka-pref. was safe) Magnitude 8.8 was very huge.

Our new family !

Image
He is our new family and he is our first baby! He was born on 28 May, and this Wednesday he came our home from hospital and 4 days had passed. He is very very bouncing baby so my wife couldn't sleep well, but we love him very much. He cried very loudly so we tried to ease him in various ways, and this picture is one of ways to be quiet. (this red material is a rattle and if I shake this rattle, he is very curious about it and hear this rattle's sound and sometimes stop crying!)

Goldsmith College, UK

Image
When I was a graduated student, I went to London and enjoyed summer school at Goldsmith college for about a month, because I wanted to spend good time at that period. Goldsmith college was located near New Cross station and I stayed at dormitory of this college, because at summer time, dormitory was empty due to the summer vacation time. And I happened to watch Flickr yesterday and search the word "New Cross", then found Goldsmith College's & around this area's picture and felt longing for this town. New Cross is located about half an hour from central London by train, so it is very convenient place to go around central London. And this town is not so big (in another saying, feel a little deserted-looking), so I enjoyed the fist experience of abroad in a relaxing mode, so I liked this town very much. If you see this picture , you can see the dormitory(*) where I stayed about 20 years ago, so I am deeply moved. (*) UK's college is started at September, s...
